Abstract

PURPOSE: To improve image quality in a scanning system using plural beams, by disposing light points for scanning on the straight line crossing at a acute angle in the direction orthogonal to the scanning direction on the surface to be scanned and determining the angle of their intersection in such a manner that the spacing between the scanning lines becomes as small as possible.
CONSTITUTION: A plurality of light sources S1WS3 are disposed on a straight line 6 inclined by an acute angle θ with respect to the direction 5 orthogonal to the scanning direction in such a manner that the spacing between the scanning lines by the light points P1WP3 for scanning on the straight line crossing at the angle θ with respect to the direction 3-1 orthogonal to the scanning direction shown by arrows on the surface 2 to be scanned. The mutual deviations of the light points P1WP3 for scanning are adjusted by deviating the timings of modulation of the respective intersection points for scanning. Thereby, the laser printer of a high speed and good quality may be constituted by using a miniature and inexpensive semiconductor laser.
