Abstract
An example image forming apparatus includes a main body having a guide frame to guide a toner cartridge on a path for detachment and attachment, a sensor to sense a remaining toner level of the toner cartridge, and a shutter member disposed to move along the guide frame in association with the attachment and detachment of the toner cartridge. In response to separation of the toner cartridge from the guide frame, the shutter member is movable to a first position covering the sensor and, in response to the toner cartridge being mounted on the guide frame, the shutter member is movable to a second position to open the sensor.
