ABSTRACT:
An electrophotographic printing device using a light source for emitting predetermined light and a photosensitive material on which an electrostatic latent image is formed by the light from the light source. The electrophotographic printing device has a memory for storing density control information on light intensity of the light source and density of an image formed on a printing medium, and a light intensity controller for controlling the light intensity of the light source based on the information in the memory. The density control information stored in the memory is determined from a relationship between the density of the image to be formed and potential of the electrostatic latent image, and a relationship between the potential of the electrostatic latent image and the light source.
