<P>PROBLEM TO BE SOLVED: To make the replacement period of a plurality of light sources even in an image forming apparatus. <P>SOLUTION: A mirror 42 can emit each of beams Ba to Bc emitted from the plurality of light sources by switching between all of a plurality of photoreceptor drums 4Y, 4M, 4C, and 4K. A control section controls the mirror 42 such that, when an electrostatic latent image is formed on the photoreceptor drum 4Y, 4M, 4C, and 4K, a plurality of the beams Ba, Bb, and Bc are emitted to each of the different photoreceptor drums 4Y, 4M, 4C, and a plurality of the photoreceptor drums 4Y, 4M, 4c, and 4k emitted by a plurality of the beams Ba to Bc are switched. <P>COPYRIGHT: (C)2012,JPO&INPIT |
