<P>PROBLEM TO BE SOLVED: To reduce the size of an exposure apparatus and to improve the layout latitude of other devices to be disposed around an exposure object. <P>SOLUTION: An angle α1 (center angle of an arc) is formed between straight lines connecting the axial center G of a photoreceptor drum 12 and ends in both sides in a width direction of an LED head 100. The smaller the angle α1 is, layout of various devices around the photoreceptor drum 12 becomes the more easily (including a charging device 14, a developing device 16, a transfer device 18, a cleaning device 20 and a destaticizing device 22 in an embodiment). That is, the latitude for design is increased. A second substrate 170 is disposed almost parallel to a first substrate 150 leaving a gap therebetween. Even when the angle α1 is small, the second substrate 170 can be made wider than the first substrate 150. Further, the angle α1 is not influenced even when a thick component such as a connector 174 is mounted on the second substrate 170. <P>COPYRIGHT: (C)2007,JPO&INPIT |
