<p><P>PROBLEM TO BE SOLVED: To provide a light emitting device which can achieve a reduced load of maintenance and also a saved space, and to provide an image forming apparatus. <P>SOLUTION: An exposure head H of an exposure device 20 is formed by forming a plurality of light emitting parts Ha for exposure at a flexible substrate 30, and winding them in a roll shape. The exposure head H wound in the roll shape is set at a driven roller R1. A winding start end of the exposure head H set at the driven roller R1 is coupled to a winding roller R2. When a rotation knob D is operated, the exposure head H wound in the roll shape is taken up to the winding roller R2. At this time, a plurality of the light emitting parts Ha formed at the exposure head H can be disposed sequentially at working positions. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
