Abstract
An image forming apparatus includes a photosensitive member, a charging member, an electrostatic latent image forming member, a developing member, a transferring member, and a cleaning device. The cleaning device includes a cleaning brush contacting with a photosensitive member to remove residual toner on the surface of the photosensitive member and a lubricant supplying brush contacting with the photosensitive member to supply a lubricant to the surface of the photosensitive member. The lubricant supplying brush is configured to change an amount of the lubricant supplied to the surface of the photosensitive member depending on a linear speed of the photosensitive member.
