Abstract
PURPOSE:To make it possible to supply toner uniformly and highly reliably to the whole surface of a toner drum by detecting the transmitted light of a light source in a sleeve with the use of a sensor which is supported in the vicinity of the outer surface of the sleeve in a manner to move in the axial direction. CONSTITUTION:Within a transparent non-magnetic sleeve 5a, there are arranged in addition to a stationary magnet 6 three light sources 11, around which a sensor 12 is supported in a manner to move in the axial direction thereby to detect the quantity of the transmitted light of the light sources 11. If the quantity of the light existing on the surface of the sleeve 5a becomes short, the quantity of the transmitted light becomes high. As a result, the sensor 12 detects the detected signals to increase the driving speed of the toner supply roller of a toner supply unit 14 through a detecting circuit S and a control circuit R so that the toner is supplied into a container 7.
