摘要： An image forming apparatus includes a housing including an opening to house a plurality of latent image bearing members for bearing latent images and latent image forming devices for forming the latent images, and an openably and closable holder to hold the latent image forming devices. The holder with one end thereof pivotally supported by the housing moves the latent image forming devices from an engaged position at which the latent image forming devices form the latent images to a retracted position at which the latent image forming devices are separated from the latent image bearing members as the holder moves to an open position at which the opening of the housing is opened. As the holder is opened, at least one of the latent image forming devices, which is closest to a fulcrum of the holder, is positioned at an end of the housing pivotally supporting the holder.

摘要： A multicolor image forming apparatus includes: a photosensitive belt unit comprising; a driving roller; a driven roller; a photosensitive belt having a joint, and a charger charging a surface of the photosensitive belt; an exposure device forming an electrostatic latent image, based on image information of each color, on the photosensitive belt; a plurality of developing devices storing different color developers, and an intermediate transfer unit performing a first transfer by sequentially superimposing each color developer image formed on the photosensitive belt. The photosensitive belt is suspended around the driving roller and the driven roller and is rotated and driven by the driving roller. Each developing device contacts and retracts from the photosensitive belt so as to develop the electrostatic latent image into a visible image using each color developer. At least one developing device can retract from the photosensitive belt at a region other than an image region.
