An audio and visual message center provides a plurality of communication devices for family members, students or co-workers. The message center has one or more visual communication devices selected from an erasable board, a calendar, a pressure sensitive adhesive surface area, a cork board, a felt pad, a clip board, a note pad or a metal surface. The message center provides an audio message communication in a record/playback device. the two-component developer comprising: toner and magnetic carrier, wherein a weight average particle diameter of the magnetic carrier is in a range of 10 μm to 80 μm, wherein a volume resistivity of the magnetic carrier is in a range of 1×108Ω·cm to 1×1015Ω·cm when a direct current voltage of 250V is applied to the magnetic carrier. 4. A two-component developer for use in an image forming apparatus including at least one latent image carrier that carries an electrostatic latent image; at least one developing device that develops the electrostatic latent image with the two-component developer to form a toner image on the at least one latent image carrier; an intermediate transfer element including an elastic layer that carries the toner image transferred from the at least one latent image carrier; a primary transfer device including the intermediate transfer element and that transfers the toner image on the at least one latent image carrier onto the intermediate transfer element; and a secondary transfer device that transfers the toner image carried by the intermediate transfer element onto a transfer material, the two-component developer comprising: toner and magnetic carrier, wherein a weight average particle diameter of the magnetic carrier is in a range of 10 μm to 80 μm, wherein a line pressure applied to the toner image transferred from the intermediate transfer element to the transfer material is in a range of 20 g/cm to 110 g/cm. 5. An intermediate transfer element for use in an image forming apparatus including at least one latent image carrier that carries an electrostatic latent image; at least one developing device that develops the electrostatic latent image with developer to form a toner image on the at least one latent image carrier, the developer including toner and magnetic carrier, and a weight average particle diameter of the magnetic carrier being in a range of 10 μm to 80 μm; a primary transfer device including the intermediate transfer element and that transfers the toner image on the at least one latent image carrier onto the intermediate transfer element; and a secondary transfer device that transfers the toner image carried by the intermediate transfer element onto a transfer material, the intermediate transfer element comprising: an elastic layer having a rubber hardness in a range of 40 degrees to 70 degrees in JIS-A of Japanese Industrial Standards, and having a thickness in a range of 50 μm to 300 μm, wherein a volume resistivity of the magnetic carrier is in a range of 1×108Ω·cm to 1×1015Ω·cm when a direct current voltage of 250V is applied to the magnetic carrier. 6. An intermediate transfer element for use in an image forming apparatus including at least one latent image carrier that carries an electrostatic latent image; at least one developing device that develops the electrostatic latent image with developer to form a toner image on the at least one latent image carrier, the developer including toner and magnetic carrier, and a weight average particle diameter of the magnetic carrier being in a range of 10 μm to 80 μm; a primary transfer device including the intermediate transfer element and that transfers the toner image on the at least one latent image carrier onto the intermediate transfer element; and a secondary transfer device that transfers the toner image carried by the intermediate transfer element onto a transfer material, the intermediate transfer element comprising: an elastic layer having a rubber hardness in a range of 40 degrees to 70 degrees in JIS-A of Japanese Industrial Standards, and having a thickness in a range of 50 μm to 300 μm, wherein a line pressure applied to the toner image transferred from the intermediate transfer element to the transfer material is in a range of 20 g/cm to 110 g/cm. 7.
