ABSTRACT:
A device for informing whether fresh toner should be newly supplied into a developer (20) into an electrophotography machine comprises a sleeve (22) for delivering toner (29) to a photosensitive drum, a blade (23) for regulating the distribution of the toner deposited on the sleeve (22), an agitator (24) for agitating the toner, a hopper (21) for loading the toner, a lever (25) with an upper projection (26) and lower support (27) pivotally moved with a pivot pin (25') attached on an inside wall (21') of the hopper (21) towards the sleeve (22), a metal plate (28) supported by the lower support (27), an actuator (32) with a magnet (36) and light shield (34) pivotally moved with another pivot pin (35), and a photosensor (31). Wherein, if the hopper (21) is devoid of the toner by consuming, the magnet (36) is attracted towards the metal plate (28) so as to cause the light shield (34) to block the photosensor (31).
