Abstract
An image forming apparatus includes: an image carrier; an image forming unit configured to form, on the image carrier, an electrostatic latent image; a developing unit including a toner carrier configured to develop, on the image carrier, a toner image corresponding to the electrostatic latent image; an application unit configured to apply a lubricant onto the image carrier; a calculation unit configured to calculate an image portion ratio representing a ratio of a toner sticking region to the electrostatic latent image or the toner image; and a control unit configured to cause the lubricant mixed into the developing unit to stick to the toner carrier, and change, depending on the image portion ratio, an amount of the lubricant caused to stick to a non-image-formation region which is a region on the image carrier and in which the electrostatic latent image or the toner image is not formed.
