Image forming device that facilitates maintenance of waste toner storage member

摘要

An image forming device includes: a cartridge; a supporting member; a belt unit; a waste toner storage member; and a conveying member. The cartridge is configured to retain a photosensitive body. The belt unit includes a belt; and a cleaning member. The cleaning member removes residual toner remaining on the belt. The waste toner storage member stores the residual toner. The belt unit is movable between a contact position in which the belt contacts the photosensitive body and a separated position in which the belt is separated from the photosensitive body. The conveying member allows the residual toner to be conveyed from the cleaning member to the waste toner storage member when the belt unit is in the contact position, and interrupts the residual toner from being conveyed from the cleaning member to the waste toner storage member when the belt unit is in the separated position.
