Abstract

An image forming apparatus includes a rotary including a developing roller and a storage portion, a toner cartridge, a support member movable between a first position and a second position, a drive source configured to move the support member in a first direction and in a second direction, a detection mechanism including a moving member and a sensor portion, and a controller. The controller is configured to determine that the support member is in the second position in a case where movement direction of the support member by the drive source is the first direction and the sensor portion is in the first detection state, and to determine that the support member is in the first position in a case where the movement direction of the support member by the drive source is the second direction and the sensor portion is in the first detection state.
