Abstract
A lubricant application device includes an application roller with application bristles radially arranged about an outer circumferential surface thereof for receiving a lubricant from a lubricant supply source and applying the lubricant to a photosensitive body. A minimum distance between the outer circumferential surface of the application roller and the photosensitive body is shorter than a length of the application bristles. The lubricant application device has a drive unit for rotating the application roller and a controller for controlling the drive unit. The controller is adapted to control the drive unit to counteract a bristle-bending tendency of the application bristles.
