Abstract
An image-forming apparatus includes: a main casing; a drawer movable in a first direction relative to the main casing; a process cartridge detachably mountable on the drawer; and a toner cartridge. The drawer includes a first drawer side plate and a second drawer side plate spaced apart from each other in a second direction crossing the first direction. The process cartridge includes: a photosensitive drum rotatable about an axis extending in the second direction when the process cartridge is mounted on the drawer; and a developing device for supplying toner to the photosensitive drum. When the process cartridge is mounted on the drawer and the toner cartridge is attached to the process cartridge, the toner cartridge has a length in the second direction greater than a distance in the second direction between the first drawer side plate and the second drawer side plate.
