ABSTRACT:
Disclosed is a method of electrophotographic image formation according to which images of high quality can be reproduced with always stable density. This method which includes the step of image formation which comprises forming a static latent image on a photoreceptor by carrying out charging and exposing and then developing is characterized in that maximum image density is maintained constant by measuring surface potential of maximum image density portion just before development and setting developing bias potential based on the above measured surface potential so that difference between the surface potential and developing bias potential becomes constant.
