Image data is inputted from a data processing means 123 into storage means 124 so that light emitting elements of one line 128 a of a light-emitting element (yellow) line head 128 are activated to expose pixels on an image carrier according to an output signal form a shift resistor 124 a. The image carrier is moved in the direction of arrow X in such a manner that the pixels reach a position corresponding to the light emitting elements in a next line 128 b. At this point of time, the image data are transmitted to a shift resistor 124 b and then outputted to the line 128 b so as to expose the pixels again. The image data are transmitted among the shift resistors sequentially by moving the image carrier, thereby sequentially repeatedly expose the same pixels.
