ABSTRACT:
An image forming apparatus wherein an image material is exposed and read by a line-configured photosensor. The line readings by the photosensor are converted into electrical signals which are put out in serial form. In one embodiment the image material is moved at a predetermined speed for scanning wherein the exposure and photosensor devices are fixed. Also, the photosensor may have a width which is the same as the image width of the image material, and these features permit accurate readings even from reduced size image material. In another embodiment a register is provided to permit a presetting of the number of lines to be read.
