<P>PROBLEM TO BE SOLVED: To accurately position an exposure member relative to a photoreceptor while solving a problem on environmental load or economic efficiency or the like. <P>SOLUTION: A color printer 1 includes: a plurality of process cartridges 50 having a photoreceptor drum 53; a support frame 100 attachably/detachably supporting the process cartridge 50 and constituted to be drawn out from a body housing 10; and a plurality of LED units 40 capable of moving between an exposure position and a retreat position, and having a plurality of light emitting parts, which are arrayed, so as to expose the photoreceptor drum 53. The support frame 100 includes a pair of side frames 100A opposed in a main direction where the light emitting parts are arrayed. Guide grooves 140 having a guiding part 141 guiding the LED unit 40 moving between the exposure position and the retreat position are respectively formed in the pair of side frames 100A. The guide groove 140 includes a positioning part 142 positioning the LED unit 40 in a sub direction orthogonal to the main direction and an exposure direction. <P>COPYRIGHT: (C)2009,JPO&INPIT |
