The image forming apparatus includes an opening and closing device that can be opened or closed with respect to a main body of an image forming apparatus, a plurality of image forming devices, a recording material containing device which contains a recording material and which can be detachably mounted on the main body, and a positioning device which positions the opening and closing device in an open state. By this arrangement, the ability to detach the image forming devices is improved without increasing the dimensions of the apparatus.

What is claimed is: 1. An image forming apparatus comprising: an opening and closing device that is capable of being opened or closed with respect to a main body of the image forming apparatus; a support member which pivotably supports said opening and closing device; a plurality of image forming devices capable of being detachably mounted on the main body in a state where said opening and closing device is opened; a recording material containing device which contains a recording material and which is capable of being detachably mounted on the main body, wherein said plurality of image forming devices are provided above said recording material containing device, wherein a surface of the main body for attaching or detaching said recording material containing device is the same as a surface of the main body for attaching or detaching said plurality of image forming devices, wherein a detaching direction of said plurality of image forming devices is inclined upwards, while a detaching direction of said recording material containing device is substantially horizontal; and a positioning device configured to position said opening and closing device by regulating movement of said opening and closing device when said opening and closing device is opened around said support member, wherein said positioning device positions said opening and closing device in a space defined between the inclined-upward detaching direction of said plurality of image forming devices and the substantially horizontal detaching direction of said recording material containing device. 2. An image forming apparatus according to claim 1, wherein said support member is a shaft and said opening and closing device is movable about said shaft provided in a substantially horizontal direction. 3. An image forming apparatus according to claim 2, wherein said opening and closing device is opened from above to below. 4. An image forming apparatus according to claim 1, wherein each of said plurality of image forming devices is a cartridge integrally including a photosensitive member and at least an image forming member acting on said photosensitive member, and a plurality of said cartridges correspond respectively to different colors. 5. An image forming apparatus according to claim 1, further comprising a conveying member opposed to said plurality of image forming devices, wherein said conveying member moves in linkage with an opening or closing operation of said opening and closing device. 6. An image forming apparatus according to claim 5, wherein said conveying member is a belt. 7. An image forming apparatus according to claim 1, wherein the direction of arrangement of said plurality of image forming devices is inclined from the vertical direction, and an image forming device positioned above another image forming device is spaced further from said opening and closing device than said another image forming device. 8. An image forming apparatus according to claim 7, wherein the direction of arrangement of said plurality of image forming devices is substantially perpendicular to an attaching or detaching direction of said plurality of image forming devices. 9. An image forming apparatus according to claim 1, wherein one of said plurality of image forming devices is provided above another of said plurality of image forming devices.
