摘要:
A color image forming apparatus wherein an image retainer (1, 120, 400) and a transfer member (5, 150, 500) are arranged unitarily in a process cartridge (130, 430), the process cartridge (130, 430) being formed so that it can be inserted into and withdrawn from an apparatus body having a plurality of developing devices (122, 422). The process cartridge (130, 430) has a cleaning device (129, 429) and a transfer member (5, 150, 500), and the apparatus body has a device (163′, 451′) for recovering waste toner. The waste toner scraped off from a surface of the image retainer (1, 120, 400) by the cleaning device (129, 429) is recovered into a hollow in the transfer member (5, 150, 500).
摘要:
A cleaning member (8) carrying porous particles for absorbing a parting agent is used in an electrophotographic apparatus having a fixation unit in which a developer image transferred to a transfer member is fixed by a fixation rotary member to which the parting agent is applied, and means for forming an image on two surfaces of the transfer member. The cleaning member (8) is either cleaning the photosensitive drum (1) or the transfer drum (5). The porous particles present in the cleaning member (8) absorbe the parting agent, e.g. silicone oil which has been attached to the transfer sheet member during fixation after the first transfer of an image in a duplex process.

摘要:
This patent specification describes a novel document illumination apparatus which includes a first light source configured to emit a bundle of light rays, a first lower reflector configured to reflect the bundle of the light rays emitted from the first light source, a first upper reflector configured to reflect the bundle of light rays reflected at the first lower reflector, to gather the bundle of the light rays and to illuminate directly a document and a first nonreflective area, which is located out of a path of the bundle of the light rays, arranged between the first lower and upper reflectors.
