Abstract
An image forming apparatus is provided, which includes: a photosensitive drum that bears an electrostatic latent image; a charging roller that charges the photosensitive drum; and a developing roller that develops by toner the electrostatic latent image formed on the photosensitive drum, a control unit that controls to start rotation of the photosensitive drum and the developing roller in a state of being in contact with each other, and an estimating unit configured to estimate a value relating to an amount of toner consumption in the image forming apparatus, on the basis of a value relating to an amount of toner that is consumed in a case in which the photosensitive drum and the developing roller are driven in the state of being in contact with each other at a time of startup of the image forming apparatus.
