Abstract
An image forming apparatus includes: a rotatable image carrier; an image forming unit configured to form an electrostatic latent image on the image carrier based on information defining at least one of a toner region and a non-toner region; a development unit configured to develop the electrostatic latent image as a toner image; a cleaning unit configured to remove toner remaining on the image carrier, after transfer of the toner image; an application unit configured to apply lubricant on the image carrier; and a hardware processor configured to control an amount of the lubricant applied, calculate a ratio of a toner region for each of regions obtained by dividing a surface of the image carrier in a direction perpendicular to a rotation direction of the image carrier, and control the amount of the lubricant applied according to a difference between a maximum value and a minimum value of the ratio.
