Abstract
A cleaning device includes a cleaning blade configured to clean a surface of a rotating subject, a solid lubricant configured to reduce the friction coefficient of the surface of the subject, and a lubricant coating device that includes a coating roller to shave the solid lubricant during normal rotation and a reverse rotation to coat the surface of the subject with the lubricant. The amount of lubricant supplied to the subject during normal rotation of the coating roller is different from a supply amount of the lubricant during reverse rotation of the coating roller, with more lubricant supplied during reverse rotation than during normal rotation.
