The drum unit is movable through the opening between an accommodated position where the drum unit is positioned in the housing and a pulled-out position where the drum unit is pulled out of the housing. The drum unit includes a photosensitive drum and a developing unit. The photosensitive drum is rotatable about a first axis extending in a second direction. The developing unit includes a magnetic roller, a developer container, a first auger and a second auger. The magnetic roller is positioned between the toner cartridge and the photosensitive drum. The magnetic roller faces a surface of the photosensitive drum. The developer container is formed with an inlet allowing the toner to be replenished from the toner cartridge. The first auger is positioned in the developer container. The second auger is positioned in the developer container.
