ABSTRACT:
In a laser beam printer wherein the quantity of light of the laser beam is fed back to maintain the light quantity at a constant value, the temperature sensor means is provided for detecting the temperature of the photosensitive member, and the feedback circuit is so constructed that the light quantity setting reference signal of the circuit is adjusted in accordance with the output of the temperature sensor means. Consequently, the quantity of light of the laser beam is adjusted according to the temperature-sensitivity characteristics of the photosensitive member to give a constant image density.
