Abstract: A toner level detector includes a toner cartridge, an agitator, a reflective region, a first cleaner, a second cleaner and a transceiver. The toner cartridge stores toner, and has a light-permeable region. The agitator rotatably disposed in the toner cartridge agitates the toner. The reflective region is disposed on the agitator. The first cleaner is disposed on the agitator. The second cleaner is disposed on the toner cartridge. The transceiver disposed on a body outside the toner cartridge outputs an emitting signal to the reflective region through the light-permeable region. The reflective region reflects the emitting signal to generate a reflective signal received by the transceiver through the reflective region. The rotating first cleaner intermittently cleans the fixed light-permeable region, and the fixed second cleaner intermittently cleans the rotating reflective region.
