A color image forming apparatus wherein an image retainer and a transfer member are arranged unitarily in a process cartridge, the process cartridge being formed so that it can be inserted into and withdrawn from an apparatus body having a pluralilty of developing devices. The process cartridge has a cleaning device and a transfer member, and the apparatus body has a device for recovering waste toner. The waste toner scraped off from a surface of the image retainer by the cleaning device is recovered into a hollow in the transfer member.

Color image forming apparatus having interchangeable image forming

An object of the invention is to provide a color image reading device having a lens unit for introducing an color image, an optical prism for separating the color image into a plurality of optical image components, and a plurality of CCDs for converting the optical image components into image signals in which the CCDs are attached to projection surfaces of the optical prism by using adhesive materials.

Image reading device

This application discloses an electrophotographic developing device having an electrode located at the developing station oppositely to an electrostatic latent image bearing body wherein said electrostatic latent image is developed with a developer that consists of an electrically conductive carrier and toner. Development occurs while applying a bias voltage between said body and said electrode which has an insulation layer on its surface.
