摘要： 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.
摘要翻译：本发明的电子照相图像形成装置包括在其表面上设置有光电导层的感光鼓。充电器对鼓的表面均匀充电，而曝光单元暴露滚筒的带电表面，从而在滚筒上形成潜像。显影装置通过将调色剂供给到滚筒来显影潜像，由此产生相应的调色剂图像，并且在图像转印之后收集留在滚筒上的剩余调色剂。图像转印装置将调色剂图像从鼓转印到中间图像转印体。空调单元将除湿的空气控制空气发送到所述光电导元件周围的空间。

摘要： 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.

摘要： 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. By further providing a contact/detach mechanism adapted to detaching movements, within said image forming apparatus, of the image bearing member holding component and the second image bearing member holding component in relation to the image forming unit holding component, the mechanism is greatly simplified with relatively simple and less expensive construction of the mechanism disclosed herein, through eliminating plural contact/detach mechanisms separately provided for the noted holding components and also providing one integrating power sources for use in driving plural units in common. As a result, the previously known disadvantage in image forming apparatus such as contact residue images which are unduly caused by continual contact of the photoreceptors to image forming units and intermediate transfer belt can be obviated, as an example.
