Abstract

The present invention provides a rotor supporting member, a photoreceptor unit including the same, and an image forming apparatus. The rotor support member is attached to a support body. The support body includes a guide that supports the first member and the second member so that the first member and the second member can move toward the rotor. The first member includes a rotation shaft and rotates about its rotation shaft while being in contact with the rotor. The second member includes a rotation shaft extending along the rotation shaft of the first member and cleans the surface of the first member while rotating in contact with the first member. The rotor support member includes a first support member that rotatably supports the rotation shaft of the second member, and a second support member that rotatably supports the rotation shaft of the first member. While the first support member and the second support member abut against each other, the first support member and the second support member respectively support the rotation shaft of the second member and the rotation shaft of the first member.

Description

technical field [0001] The present invention relates to a rotor supporting member, a photoreceptor unit including the rotor supporting member, and an image forming apparatus. Background technique [0002] There is known a charging device that includes: a charging member that charges the surface of a charging target while rotating in contact with the charging target; a cleaning member that includes a The shaft rotates and removes unnecessary substances from the surface of the charging member while being rotated in contact with the charging member; and a supporting member including: a first receiving portion having an opening at one end thereof and a concave shape having a bottom at one end; and a second receiving portion having a concave shape open at one end thereof and having a bottom at the other end thereof. The first receiving portion receives the outer peripheral surface of the rotating shaft of the charging member at the bottom thereof. The second housing part accomm...
