description A toner density control apparatus wherein an image density of a reference image on a photosensitive member is compared with a predetermined level to control a toner density, a voltage to be applied on a light-emitting element is controlled according to a difference between an output of a light-receiving element when it receives a light reflected from a non-image surface region on the photosensitive member and correction reference data, and a signal is supplied to the outside when the voltage is increased more than a predetermined value.
