<P>PROBLEM TO BE SOLVED: To save a space and effectively cool each component in an image forming device. <P>SOLUTION: Polygon motors 30Y, 30M, 30C, 30K of exposure portions 3Y, 3M, 3C, 3K are housed in projections 3Ym, 3Mm, 3Cm, 3Km, arranged in a manner projecting from a partition member 40 to a development unit side. The projections 3Ym, 3Mm, 3Cm, 3Km are arranged to overlap at least end portions of development units 4Y, 4M, 4C, 4K in plane face. Accordingly, the projections 3Ym, 3Mm, 3Cm, 3Km of the exposure portions 3Y, 3M, 3C, 3K and the development units 4Y, 4M, 4C, 4K are arranged alternately in vertical direction, enabling effective cooling. <P>COPYRIGHT: (C)2013,JPO&INPIT |
