    • Disclosed is the prevention of the occurrence of uneven image density, as well as the image degradation caused by inhibiting the continuity of image density, produced by the photoreceptor in which uneven electrification exists, and additionally uneven sensitivity coexists, without enlargement of the apparatus as well as increase in the cost. To the exposure amount obtained by the approximate linear transformation of the pixel gradation in each segment multi-divided in the surface of the photoreceptor drum 1, in all the pixel gradation including 0 level, exposing source 2 is controlled to expose with the amount of exposure, offset with only the offset exposure amount Ea which corresponds to the difference between the initial electric potential and the reference initial electric potential V0 of the segment. The exposure amount adjustment of the offset exposure amount Ea is conducted by offsetting the exposure time in each pixel.

    • Uneven image density produced by photoreceptors, in which uneven electrification and sensitivity coexist, is limited economically and space efficiently. For each segment of the surface of the photoreceptor, individual memorizing of slope information K1 defining the slope of when a pixel gradation is approximately linear-transformed into exposure amount and, based upon K1 per segment, individual transforming of pixel gradation into the exposure amount (individual exposure amount transformation) is performed. The slope information which, with a reference electric potential Vs1 , matches the electric potential after the exposure of when the exposure amount, obtained by transforming a reference pixel gradation Is1 by means of the individual exposure amount transformation, is applied to the approximately-linear exposure property excepting the converging region to a residual potential VL, or to the exposure property extended by extrapolation operation, among exposure property g01 showing correspondence between the exposure amount and the electric potential after exposure per segment.
