Abstract
An image carrier unit includes an image carrier including a cylindrical main body portion and a pair of flange portions attached to both ends of the main body portion, a first cleaning member that rotates in contact under a prescribed pressure with an outer circumferential surface of the main body portion, a unit frame that rotatably supports the image carrier and the first cleaning member, and an image carrier protective cover that includes a cover main body extending in an axial direction of the image carrier and a side surface portion that is disposed on one end side of the cover main body. On the side surface portion, an image carrier holding portion is formed that performs positioning of the image carrier with respect to the unit frame and releases a pressure contact state between the image carrier and the first cleaning member.
