Abstract
To provide an image forming apparatus in a new form developed from a conventional technique.SOLUTION: An image forming apparatus has: a photoconductor drum; an exposure device that exposes a surface of the photoconductor drum to form an electrostatic latent image on the surface; a rotatable rotary that has a developing roller for developing the electrostatic latent image as a toner image, and a storage frame body including a storage unit for storing toner supplied to the developing roller; a toner cartridge that stores the toner and is removably attached to the rotary; a recovery member that, after the toner image is transferred from the photoconductor drum, recovers waste toner adhering to the photoconductor drum; and a waste toner storage unit that stores the waste toner recovered by the recovery member. The waste toner storage unit is arranged to at least partially overlap the exposure device when seen in a rotation axis direction of the photoconductor drum.SELECTED DRAWING: Figure 13
