Abstract
An image forming apparatus includes an image bearer to bear a toner image, a lubricant supply roller to supply lubricant to a surface of the image bearer, a rotation speed changer to change a rotation speed of the lubricant supply roller, and a controller to control the rotation speed changer to change the rotation speed of the lubricant supply roller to a target speed based on a predetermined condition. The controller is configured to control the rotation speed changer to avoid a predetermined speed range.
