A rotor bearing member is attached to a support body. The support body includes a guide section that supports a first member and a second member such that the first member and the second member are movable toward a rotor. The first member includes a rotary shaft and rotates about the rotary shaft thereof while being in contact with the rotor. The second member includes a rotary shaft extending along the rotary shaft of the first member and cleans a surface of the first member while rotating in contact with the first member. The rotor bearing member includes a first bearing member and a second bearing member that rotatably support the rotary shaft of the second member and the rotary shaft of the first member, respectively, while the first bearing member and the second bearing member abut each other.

An image forming device includes an image carrier, a cleaning device, a charging device and a shielding member. The image carrier carries a toner image thereon. The cleaning device removes a toner on the image carrier. The charging device charges the image carrier. The shielding member is disposed between the cleaning device and the charging device. The shielding member is in contact with the image carrier in an area where the image carrier is charged.

A grid electrode, disposed along a corotron wire, includes a planar, plate-shaped member having plural openings in each of which a longitudinal direction and a short side direction are formed, the longitudinal directions of the respective openings being lined up to be in a same direction, and connecting portions connecting openings adjacent to each other in a opening longitudinal direction and connecting portions connecting openings adjacent to each other in a opening short side direction. At each opening, a shortest distance from a center point to an opening edge is less than 1.5 mm, a grid opening ratio is greater than or equal to 82%, and a length of the longitudinal direction is at least 1.3 times a length of the short side direction. The connecting portions connecting openings adjacent to each other in the opening longitudinal direction are not disposed on a same line which is orthogonal to the corotron wire.
