An image forming apparatus includes a first moving member pressed and moved by an openable/closable member when the member is opened. A cartridge is switched from being positioned in an image forming position to a state where the positioning is released. A second moving member is pressed and moved by the openable/closable member when the member is opened, and the exposure member is moved from an exposure position to a retracted position. When the cartridge is released, a reaction force applied from the first moving member to the openable/closable member reaches a first peak. When the exposure member is moved to the retracted position, a reaction force applied from the second moving member to the openable/closable member reaches a second peak. Timing of the first peak is different from timing of the second peak.

The image forming apparatus according to claim 1, wherein the openable and closable member presses and moves the first moving member and then presses and moves the second moving member. 3. The image forming apparatus according to claim 1, wherein the first moving member is pressed and moved by the openable and closable member to position the cartridge in the image forming position when the openable and closable member is closed, the second moving member is pressed and moved by the openable and closable member to move the exposure member to the exposure position when the openable and closable member is closed, andtiming when the openable and closable member presses the first moving member to position the cartridge in the image forming position is different from timing when the openable and closable member presses the second moving member to move the exposure member to the exposure position. 4. The image forming apparatus according to claim 3, wherein the first moving member and the second moving member are moved by a toggle mechanism. 5. An image forming apparatus in which a cartridge that supports a photosensitive member is mounted to an image forming position, and which forms a latent image on the photosensitive member by exposure to form an image, the apparatus comprising: an exposure member that includes a light emitting element arranged in an array, and exposes the photosensitive member of the cartridge located in the image forming position in an exposure position;an openable and closable member that can be opened or closed with respect to a main body of the apparatus, and can mount the cartridge to the main body of the apparatus in a state of being opened with respect to the main body of the apparatus;a first moving member that is pressed and moved by the openable and closable member when the openable and closable member is closed, and positions the cartridge in the image forming position; anda second moving member that is pressed and moved by the openable and closable member when the openable and closable member is closed, and moves the exposure member in an arrangement direction of the cartridge and the exposure member and moves the exposure member to the exposure position,wherein, while the openable and closable member is being closed, when the first moving member positions the cartridge in the image forming position, a reaction force applied from the first moving member to the openable and closable member reaches a first peak, and when the second moving member moves the exposure member to the exposure position, a reaction force applied from the second moving member to the openable and closable member reaches a second peak, andtiming of the first peak is different from timing of the second peak. 6. The image forming apparatus according to claim 5, wherein the openable and closable member presses and moves the first moving member and then presses and moves the second moving member. 7. An image forming apparatus in which a cartridge that supports a photosensitive member is mounted to an image forming position, and which forms a latent image on the photosensitive member by exposure to form an image, the apparatus comprising: an exposure member that includes a plurality of light emitting elements arranged in an array, and exposes the photosensitive member of the cartridge located in the image forming position by the plurality of light emitting elements in an exposure position;a first moving member that is urged to move the cartridge in a direction different from an insertion direction of the cartridge into the main body of the apparatus when the cartridge is mounted to the main body of the apparatus; anda second moving member that is pressed by the cartridge to urge the exposure member and moved to a positioning position to position the exposure member in the exposure position when the cartridge is mounted to the main body of the apparatus,wherein the cartridge is moved by the first moving member and moved toward the image forming position,wherein, while the cartridge is being inserted into the main body of the apparatus, when the cartridge presses the first moving member against a force of urging the first moving member, a reaction force applied from the first moving member to the cartridge reaches a first peak, and when the cartridge presses the second moving member and moves the second moving member to the positioning position, a reaction force applied from the second moving member to the cartridge reaches a second peak, andtiming of the first peak is different from timing of the second peak. 8. The image forming apparatus according to claim 7, wherein the first moving member moves the cartridge upward. 9. The image forming apparatus according to claim 8, wherein, when the first moving member moves the cartridge upward by a predetermined amount, and then the cartridge is further inserted into the main body of the apparatus, the cartridge is pressed by the exposure member moved by the second moving member and further moved upward and reaches the image forming position. 10. The image forming apparatus according to claim 7, wherein the cartridge is moved along a rotating axis direction of the photosensitive member and inserted into the main body of the apparatus. 11. The image forming apparatus according to claim 10, further comprising a cartridge placement member that is drawn from the main body of the apparatus and on which the cartridge can be placed, wherein, when the cartridge is mounted to the main body of the apparatus, the cartridge placed on the cartridge placement member is inserted into the main body of the apparatus, and the cartridge presses the second moving member via the cartridge placement member to move the second moving member to the positioning position. 12.
