<p><P>PROBLEM TO BE SOLVED: To provide an image forming apparatus which can control a degradation of an image quality by suppressing effects of oscillation to an exposure unit. <P>SOLUTION: The image forming apparatus includes an LED unit 40 which exposes a photoreceptor drum 53, a pressing spring 45 which presses the LED unit 40 towards the photoreceptor drum 53, a first positioning member 110 which determines a position of the LED unit 40 in a back-and-forth direction by contacting to the LED unit 40, a second positioning member 120 which is arranged on a side nearer to the photoreceptor drum 53 than the first positioning member 110 in an up-and-down direction and determines the position of the LED unit 40 in the back-and-forth direction by contacting to the LED unit 40, and a second pressing member 46 which presses the LED unit 40 towards the second positioning member 120. A point of action 45A where the pressing spring 45 presses the LED unit 40 is located on the side nearer to the photoreceptor drum 53 than the first positioning member 110 in the up-and-down direction. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
