PROBLEM TO BE SOLVED: To prevent damage caused by the rubbing of an exposure means with an image carrier or the like, at the time of attachment/detachment by regulating the attachment/detachment of the image carrier or an image forming part with respect to a device in accordance with the attachment/detachment state of the exposure means. SOLUTION: In order to set a distance between an LED array 2 and the surface of a photoreceptor 1 to a specified value, the LED array 2 is energized toward the photoreceptor 1 so as to abut on an I/C casing supporting the photoreceptor 1, whereby it is positioned. An energizing mechanism 40 capable of releasing energizing force exerted on the LED array 2 toward the photoreceptor 1 in the case of attaching/detaching an I/C 30 is provided with a bar or the like, freely sliding on an operation lever 41 operated to be rotated. The I/C 30 is detached from and attached to a device main body and arranged to cover the lever 41 with respect to an attaching/detaching port part, so that the lever 41 can not be rotated when the I/C 30 is at an imperfect position in the middle of attachment. Therefore, the LED array 2 is not energized toward the I/C casing. |
