Abstract: An electrophotographic image forming apparatus of the present invention includes a frame, a photoconductive drum disposed in the frame, and an air conditioning device for removing moisture around the drum inside the frame. The drum has a wear-resistant, durable surface layer that wears by an amount of 0.05 ?m to 0.5 ?m for 100,000 rotations.

Abstract: An image forming apparatus is disclosed including at least a plurality of image bearing members a plurality of image forming units each including plural image forming members for operating image forming steps onto each of the image bearing members, and a further image bearing member, which are held collectively on an image bearing member holding component. image forming unit holding component and second image bearing member holding component, respectively.

Abstract: A process cartridge detachably attached to an image forming apparatus includes an image carrier, at least one image forming process device, a case that integrally accommodates the image carrier and the at least one image forming process device, and a first non-slip holding portion provided on a partial surface of the case. The process cartridge is configured to move in a direction substantially parallel to a longitudinal direction of the image carrier. When the process cartridge is attached to and detached from the image forming apparatus, an operator of the image forming apparatus holds the process cartridge by grasping the first non-slip holding portion and a rear surface of a part of the case located on a side opposite from the first non-slip holding portion.

Abstract: An electrophotographic image forming apparatus of the present invention includes a photoconductive drum provided with a photoconductive layer on its surface. A charger uniformly charges the surface of the drum while an exposing unit exposes the charged surface of the drum to thereby form a latent image on the drum. A developing device develops the latent image with toner by feeding the toner to the drum to thereby produce a corresponding toner image and collects residual toner left on the drum after image transfer. An image transferring device transfer the toner image from the drum to an intermediate image transfer body. An air conditioning unit sends dehumidified, air-controlled air to a space around said photoconductive element.
