Charging device and image forming apparatus

1. A charging device comprising:

a charging member that charges an outer peripheral surface of a cylindrical latent-image carrier;

an electrode member including a curved portion that is formed by press working so as to extend along the outer peripheral surface of the latent-image carrier, the curved portion having an electrode to which a voltage is applied, the electrode being disposed between the charging member and the latent-image carrier;

a cleaning member that is movable along the curved portion in an axial direction of the latent-image carrier and that cleans the electrode; and

a receiving portion formed in the curved portion at a position outside the electrode, the receiving portion receiving the cleaning member to release a contact pressure between the curved portion and the cleaning member.

2. The charging device according to claim 1 , wherein the cleaning member is provided at each side of the curved portion in a thickness direction of the curved portion, and

wherein the receiving portion is a through hole formed in the curved portion.

3. An image forming apparatus comprising: the charging device according to claim 2 ;

wherein the latent-image carrier carries a latent image formed by irradiation with light, and

wherein the image forming apparatus further comprises:

a developing unit that develops the latent image with developer to form a developer image; and

a transfer unit that transfers the developer image onto a recording medium.

4. An image forming apparatus comprising:

the charging device according to claim 1 ;

wherein the latent-image carrier carries a latent image formed by irradiation with light, and

wherein the image forming apparatus further comprises:

a developing unit that develops the latent image with developer to form a developer image; and

a transfer unit that transfers the developer image onto a recording medium.
