摘要: A cleaning device, which is included in a process cartridge and an image forming apparatus, includes a cleaning blade configured to remove a material attached to a surface of an image bearer, a cleaning case configured to contain the material removed by the cleaning blade, and a removed material receiver configured to receive the material failed to enter into the cleaning case when the material is removed by the cleaning blade, the removed material receiver having a first range at both ends in a width direction of the cleaning blade and a second range at a center in the width direction of the cleaning blade. A volume per unit length in a width direction of the first range is greater than a volume per unit length in a width direction of the second range.

摘要: A device disposed opposing an image bearer includes a roller to rotate while contacting a surface of the image bearer, a rolling bearing fitted around a shaft located at an end of the roller in an axial direction of the roller, a frame to house the roller, and a bearing support removably attached to the frame. The rolling bearing includes an outer ring, an inner ring, and a rolling element disposed between the outer ring and the inner ring. The bearing support holds, from an outer-ring side, the rolling bearing interposed between the bearing support and the frame. The bearing support includes a receiving portion to contact the outer ring of the rolling bearing and bias the rolling bearing toward the frame in a direction in which the rolling bearing is interposed between the bearing support and the frame.

摘要: A charging device is detachably attachable with respect to a body of an image forming apparatus. The charging device includes a charging roller and a cleaning member. The charging roller charges an image bearer. The cleaning member cleans the charging roller. The cleaning member has a higher cleaning performance on the charging roller during detachment in which the charging device is detached from the body of the image forming apparatus than during attachment in which the charging device is attached to the body of the image forming apparatus.
