ABSTRACT:
A variable magnification electrophotographic image forming apparatus is provided with a controller for the light emission amount of the exposure lamp so as to attain a desired toner image density. The controller includes a calculator for calculating the light emission amount according to the set magnification based on a relationship between the light emission amount and the magnification amount and a correcting device for correcting the calculated light emission amoubt based on a relationship between the density of the original, the temperature of the photosensitive member, the surface potential, or the toner density in the developing unit and the toner image density.
