<p><P>PROBLEM TO BE SOLVED: To increase dot density relatively at a low cost without increasing the number of light sources of individual body light emitting array. <P>SOLUTION: A luminous flux emitted from a light emitting part (2) of the individual body light emitting array (1) is image-formed on a photo-conductor (4) by an image forming element (3). At this instance, by moving the image forming element (3) in the direction (8a) intersecting at right angles to an optical axis and in its reverse direction, the position of a dot image (5) on the face of the photo-conductor (4) is also moved. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
