Abstract: A toner level detector, includes: a toner cartridge storing toner and having one side provided with a light-permeable region; an agitator, which is rotatably disposed in the toner cartridge and agitates the toner; a reflective region disposed on an inner surface on the other side of the toner cartridge; a first cleaner disposed on one side of the agitator; a second cleaner disposed on the other side of the agitator; and a transceiver, which is disposed on a body outside the toner cartridge, and outputs an emitting signal to the reflective region through the light-permeable region, wherein the reflective region reflects the emitting signal to generate a reflective signal received by the transceiver through the reflective region, wherein the first cleaner, which is rotating, intermittently cleans the light-permeable region, which is fixed; and the second cleaner, which is rotating, intermittently cleans the reflective region, which is fixed.

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.
