ABSTRACT:
A digital half-tone image is reproduced by exposing a photoconductor by modulating the intensity of laser beam. In order to correct the effect of the size of laser beam on the gradation characteristic, the surface potential of the photoconductor is detected under various conditions. The sensitizing potential and the sensitivity of the photoconductor are corrected according to the measured values for stabilizing the gradation potential. Then, the beam size is corrected according to the surface potential or the amount of adhered toners detected under prescribed conditions, without detecting the beam size.
