Image forming apparatus including image forming condition correction arrangement and method for correcting image forming condition in image forming apparatus

摘要

In an image-forming apparatus by using electrophotographic process, a method for stabilizing an image is provided. First, a photoconductor is sensitized with a prescribed standard sensitizing potential, and the surface potential thereof is detected. Then, the standard sensitizing potential is corrected according to the detected potential. Next, latent image patterns are formed with a plurality of light-emitting powers on a photoconductor which has been sensitized with the corrected prescribed standard potential, and the surface potentials thereof are detected. Thus, a relation between the light-emitting power and the surface potential is obtained directly. Then, the light-emitting power is determined which realizes the detected surface potential nearest to the object potential. Next, a standard toner image is formed for automatic image density control by using the corrected sensitizing potential and the selected light-emitting power.
