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： An image forming apparatus includes a process cartridge that includes an image bearer including a rotary shaft and rotates about the rotary shaft; a charger to charge a surface of the image bearer; and a developing device to develop an electrostatic latent image formed on the image bearer into a visible toner image. The charger includes a charging roller that rotates about a shaft together with the image bearer during image formation and electrically charges a surface of the image bearer. A surface linear speed of the charging roller is made slower than a surface linear speed of the image bearer. The image forming apparatus includes a charging roller controller that switches the rotational speed of the charging roller to a first rotational speed slower than the linear speed of the image bearer and a second rotational speed identical to the linear speed of the image bearer.

摘要： A lubricant supplying device includes a lubricant supplier contacting an image bearer, a solid lubricant contacting the roller, a detector detecting a lubricant amount, and a controller controlling a supplying of the roller based on a detector detection. The detector outputs to the controller a first signal of a near-end state when the amount reaches a first amount, a second signal of an end state when the amount reaches a second amount smaller than the first amount, and a third signal of an absolute end state when the amount reaches a third amount smaller than the second amount. The controller temporarily stops the supplying when the second signal is output, cancels a roller temporary stopped state even when lubricant replacement is not completed after this state, stops the supplying when the third signal is output, and maintains a roller stopped state until the replacement is completed after this state.

摘要： When the acute angle between a normal line, oriented outward from a blade abutting portion of a photosensitive member over which a cleaning blade remains abutted before separation of the surface of the photosensitive member from the cleaning blade, and a horizontal plane, passing through the origin of the normal line, is expressed as a positive value when the normal line lies above the horizontal plane and expressed as a negative value when the normal line lies below the horizontal plane; an imaging unit frame so supports a photosensitive module that the photosensitive member can rotate to a specific rotational position having a greater angle than the angle at the time of separation of the surface of the photosensitive member from the cleaning blade. Until the photosensitive member rotates from a normal rotational position to the specific rotational position, the photosensitive module cannot be removed from the imaging unit frame.

摘要： A lubricant applicator includes a solid mold lubricant, a lubricant application roller, and a flicker member. The lubricant application roller scrapes and applies the lubricant to an image bearing member. The flicker member removes a powder substance adhered to the surface of the lubricant application roller and is disposed upstream of the solid mold lubricant in a direction of rotation of the lubricant application roller. The lubricant application roller, the flicker member, and the solid mold lubricant define a sealed space therebetween. A lubricant applicator includes the solid mold lubricant, the lubricant application roller, the flicker member, and an adherence prevention member that prevents the substance removed by the flicker member from adhering again to the lubricant application roller. A lubricant applicator includes the solid mold lubricant, the lubricant application roller, and a lubricant receiver that receives the scraped lubricant from the lubricant application roller.
