Abstract:
An electrostatic printing apparatus comprising a charging unit, a writing unit, a developing unit, a transfer unit, a cleaning unit, and an AC discharging unit disposed around a photosensitive body; an erasing unit for removing residual charge on the photosensitive body by use of erasing light, the erasing unit being located at any one of a position between the transfer unit and the AC discharging unit and a position between the AC discharging unit and the charging unit, whereby exposure is performed on the charged photosensitive body based on image information to form an electrostatic latent image on a surface of the photosensitive body, the latent image being converted to a visible image using toner; and means for controlling light intensity of the erasing light of said erasing unit so that the light intensity is strengthened when a density of a printed image is light and weakened when the density of the printed image is dark.
