A photosensitive body unit for an image forming device comprises: a rotatable photosensitive body; a chargeable roller including an elastic layer; a first spring which pressurizes the roller towards a drum; a driving receiving unit which is provided to the drum; and a touch unit which is touched to the driving receiving unit, and receives driving power through the driving receiving unit. The photosensitive body unit further comprises: a rotatable spacer which is rotated between a separation position which maintains a separation state separating the roller from the drum by touching the touch unit to the driving receiving unit, and a touch position which releases the separation state between the drum the roller, and is moved towards the drum; a supporting member which pressurizes the spacer in a state of positioning the spacer in the separation position; and a second spring which pressurizes the supporting member towards a rotation axis line of the spacer. |
