Abstract
Provided is a cleaning member, including a shaft material that rotates about an axial center, and a cleaning material that is spirally wound around the shaft material, is driven to be rotated by a rotating member to be cleaned, cleans the member to be cleaned, and has the number of windings which is equal to or greater than 1 and less than 2 in a cleaning area where the member to be cleaned is cleaned.
Claims6
A charging apparatus, comprising:
- a charging member as a member to be cleaned that is driven to be rotated by a rotating image holding member and charges the image holding member;
- and
- a cleaning member that is driven to be rotated by the rotating charging member and cleans the charging member, the cleaning member comprising:
- a shaft material that rotates about an axial center;
- and
- a cleaning material that is spirally wound around the shaft material, is driven to be rotated by a rotating member to be cleaned, cleans the member to be cleaned, and has the number of windings which is equal to or greater than 1 and less than 2 in a cleaning area where the member to be cleaned is cleaned, the cleaning material having a thickness and coupled to a surface of the shaft material and extending above the surface.

An image forming apparatus, comprising:
- an image holding member;
- a charging member as a member to be cleaned that is driven to be rotated by a rotating image holding member and charges the image holding member;
- a cleaning member that is driven to be rotated by the rotating charging member and cleans the charging member;
- an exposure device that exposes the charged image holding member and forms an electrostatic latent image;
- and
- a developing device that develops the electrostatic latent image formed on the image holding member,
- wherein the cleaning member comprises:
- a shaft material that rotates about an axial center;
- and
- a cleaning material that is spirally wound around the shaft material, is driven to be rotated by a rotating member to be cleaned, cleans the member to be cleaned, and has the number of windings which is equal to or greater than 1 and less than 2 in a cleaning area where the member to be cleaned is cleaned, the cleaning material having a thickness and coupled to a surface of the shaft material and extending above the surface.
