摘要:
An electrophotographic recording apparatus includes an exposing device for exposing a photosensitive member according to image data, a developing device for developing an electrostatic latent image created on the exposed photosensitive member, and a fixing device for fixing the developed image, and the exposing device includes an image data processing circuit for converting discontinuous black-level pixels included in the pixels of the image data which is constructed by a plurality of pixels selectively including black-level pixels and white-level pixels to a white level to create processed image data, and a line scanner for line-scanning the photosensitive member by a plurality of times according to the image data and the processed imaged data each time an image of one line is created so as to create an electrostatic latent image corresponding to a combination of the image data and the processed image data on the photosensitive member.
