<p>PURPOSE:To form an image superior in reproducibility even in case of optical write of one transverse dot in the subscanning direction by outputting information different in time of optical write to a recording body in accordance with recording data inputted by an optical write means. CONSTITUTION:A signal PT3 is outputted from a gate circuit 19 to a signal electrode 11a through an OR gate 14 and a microshutter 12a is closed by the signal. The waveform which closes the microshutter 12a is selected by a selecting circuit and delays opening of the microshutter 12a by a period TA of an opening signal generated by the microshutter 12a. Thus, the time when a corresponding dot on a photosensitive face 1a does not receive light, namely, the time of closing is extended as shown by J. Since the surface potential on the photosensitive face 1a remains sufficiently in the period J, a toner is stuck easily at the development time, and one dot is reproduced sufficiently.</p> |
