ABSTRACT:
The present invention relates to an image recording system for recording an image formed on an image plane onto a photosensitive member by exposure, the image plane comprising a plurality of pixels capable of changing over between a first state which permits the exposure of light to the photosensitive member and a second state in which the exposure of light to the photosensitive member is infeasible, and a non-pixel area present at a peripheral area with respect to the pixels. The size of each pixel is set such that the length of a side in a pixel pitch direction is slightly larger than one half of the pixel pitch. In this image recording system, therefore, when recording an image on the photosensitive member, an exposure position controlling means causes a relative position changing means to shift a relative position of the photosensitive member and the image plane at least three times so as to prevent recording of the non-pixel area in the image recorded on the photosensitive member.
