Abstract:
An image forming apparatus, comprising:an image carrier configured to rotate and carry an image on a surface of the image carrier; a latent image forming device configured to form an electrostatic latent image on the image carrier; a developing device configured to develop the electrostatic latent image with a developer including a lubricant; a transfer device configured to transfer the image to a transfer material; and a control device including a lubricant application executing device to at least control the lubricant application executing device to execute an application of the lubricant to the image carrier by actuating the developing device to apply the developer to the surface of the image carrier during one job of an image forming operation from a start of rotation of the image carrier to a stop of the image carrier, wherein the control device further includes an image area calculating device configured to calculate an area of an image formed on the surface of the image carrier, and wherein the lubricant application executing device executes the application of the lubricant to the surface of the image carrier based at least in part on the calculated area of the image provided by the image area calculating device.
