Cleaning body, cleaning device, charging device, assembly, and image forming device

1. A cleaning body comprising:

a shaft portion; and

a porous member that is mounted to an outer periphery of the shaft portion at an incline with respect to an axial direction of the shaft portion, and in which a plurality of cavities are formed,

wherein the porous member has projecting portions that project toward a radial direction outer side of the shaft portion in a cross-section along the axial direction of the shaft portion, and the projecting portions contact a body to be cleaned and clean the body to be cleaned, and lengths, along a radial direction of the shaft portion, of the plurality of cavities are longer than lengths along the axial direction of the shaft portion.

2. A cleaning device comprising:

the cleaning body of claim 1 that is slave-rotated due to the projecting portions of the porous member contacting the body to be cleaned that rotates, and that cleans the body to be cleaned; and

a supporting member that supports the shaft portion of the cleaning body rotatably.

3. A charging device comprising:

the cleaning device of claim 2 ; and

a charging body that serves as the body to be cleaned that rotates.

4. An assembly comprising:

the cleaning device of claim 2 ;

a body to be charged; and

a charging body that charges the body to be charged, and that serves as the body to be cleaned that rotates,

wherein the assembly is integrally assembled detachably at a device main body.

5. An image forming device comprising:

the cleaning device of claim 2 ;

an image holding body that can hold an image;

a charging body that charges the image holding body, and that serves as the body to be cleaned that rotates;

an exposure device that exposes the image holding body that has been charged by the charging body, and forms an electrostatic latent image; and

a developing device that develops the electrostatic latent image formed on the image holding body by the exposure device.
