1. An image forming apparatus comprising:
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 formed on the image carrier, 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, said hardware processor configured to: 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, based on at least one of the information input for a certain period in the past, and the information input for a certain period in the future which is expected from reserved jobs in the image forming apparatus; and control the amount of the lubricant applied according to a difference between a maximum value and a minimum value of the ratio calculated for the respective regions on the surface of the image carrier. |
