Abstract
A CPU calculates an optimum inclination angle, an optimum movingspeed (V.sub.X) and an optimum displacement time of delay timing on the basis of input signals commanding resolution, a rotation cycle (T) and the number of beams, supplied from an operating part, and outputs a control signal (V.sub.CONT4) providing the inclination angle to a motor (9). As the result, an LED holder (30) rotates with respect to a central axis (37) at the inclination angle and stops. A zoom lens (24) is adjusted by a control signal (V.sub.CONT3) providing a magnification which is responsive to the resolution. A motor (7) is driven by a control signal (V.sub.CONT2), to drive an exposure head (20) at the moving speed (V.sub.X). A cylinder (36) rotates by a control signal (V.sub.CONT1) in a subscanning direction (Y) at the rotation cycle (T). As the result, an image forming region (34) is inclined with respect to the central axis (37) at the inclination angle.
