<p><P>PROBLEM TO BE SOLVED: To provide a line head of the configuration without any difference in an emitted quantity of light of a plurality of light emitting elements, and to provide an image forming apparatus using the same. <P>SOLUTION: The plurality of light emitting elements E1-En are arranged at a light emitting element line 1. A first power supply line 2a formed by thin film wiring is connected to first feeding points 6a and 6b of a power supply (VDD) side. A second power supply line 3a formed by thin film wiring is connected to first feeding points 7a and 7b of a grounding (GND) side. Positions of the feeding points 6a and 6b are set at both end parts of the line, and positions of the other feeding points 7a and 7b are set also at both end parts of the line. A third power supply line 2b and a fourth power supply line 3b are wired in a longitudinal direction of the line, and connected to second feeding points 6c, 6d and 7c, 7d, respectively. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
