Abstract:
1. An image forming apparatus comprising an exposing head having sets of arrayed illuminants aligned along a main scanning direction, the sets of arrayed illuminants being dynamically controlled to light so as to expose an image bearing body which moves in an auxiliary scanning direction at a predetermined speed for forming an image; and a control means for lighting which dynamically controls to light the sets of arrayed illuminants according to an exposing data selected from an image data of a precedent line or from an image data of a current line based on a predetermined correcting value, wherein the control means for lighting comprises a circuit for rearranging data that rearranges image data read from a reading line buffer so as to reverse data array among adjacent sets of arrayed illuminants and communicate the rearranged image data to the exposing head and a circuit for controlling arrayed illuminants that dynamically controls to light the exposing head in accordance with the rearranged image data.
