<P>PROBLEM TO BE SOLVED: To provide an image forming device determining positions of an exposure member and a photoreceptor with a high degree of precision. <P>SOLUTION: The image forming device includes: a photoreceptor drum 52; a long LED head 41 disposed facing the photoreceptor drum 52 on which light emitting parts (LED) that emit light are aligned; and a process frame 51 that supports the photoreceptor drum 52. A columnar positioning protrusion 62 that extends along the direction of the optical axis of the light from the light emitting parts is formed on the process frame 51. A groove-like positioning concave part 43 having a V-shaped cross section engagement surface 43A that can engage with a lateral side 62B of the positioning protrusion 62 is formed on the LED head 41. The image forming device is further provided with: a leaf spring 63R for biasing the engagement surface 43A (LED head 41) toward the positioning protrusion 62. <P>COPYRIGHT: (C)2010,JPO&INPIT |
