Abstract
A method for controlling an electrophotographic copying process in order to maintain the quality of copy images uniform as well as excellent even if the gamma characteristics of a photosensitive member including a photoconductive material such as AsSe or halogen doped SeTe has been changed due to changes in temperature of the photosensitive member is provided. A main feature of the method resides in using different combinations of process variables including charging amount, exposure amount and developing bias voltage level depending upon whether the temperature of the photosensitive member goes higher or lower than a predetermined reference level.
