The lubricant supply roller is adapted to supply the lubricant to a toner image bearing member and is rotatable in a predetermined direction while slidably contacting both the solid lubricant and the toner image bearing member. The detector is adapted to detect an absolute humidity around the lubricant supply device. The varying device is adapted to vary an amount of the lubricant to be supplied to the toner image bearing member based on the absolute humidity detected by the detector.

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 lubricating device operable to lubricate a moving imaging surface subsequent to removal of residual toner by a cleaning device includes a lubricant applicator, a metering blade, and a priming agent. The lubricant applicator is located downstream of the cleaning device in a direction of movement of the imaging surface, and applies lubricant to the imaging surface. The metering blade is located downstream of the lubricant applicator in the direction of movement of the imaging surface, and spreads the applied lubricant into a thin layer by directly contacting the imaging surface. The priming agent is prepared by mixing a lubricant and a powder, and provided, prior to initial operation, on the lubricant applicator for application to the imaging surface upon startup.
