Abstract
An image forming apparatus includes an image carrier, a cleaning device having a cleaning member that comes into contact with a surface of the image carrier, and a lubricant applying device provided on the downstream side of the cleaning member. The lubricant applying device includes a solid lubricant, a lubricant supply roller, and a trailing type lubricant smoothing blade that is provided on the downstream side of the lubricant supply roller, and comes into belly contact with the surface of the image carrier. After image carrier is stopped, constantly or under a predetermined condition, the surface of the image carrier is moved in a direction opposite to an image forming direction. The opposite movement distance is equal to or more than the shortest distance between a contact point between the lubricant supply roller and the image carrier and a contact point between the lubricant smoothing blade and the image carrier.
