Abstract

A lubricant applying device, includes: an image carrier; a lubricant; a lubricant applying member that contacts the image carrier and the lubricant, and maintains a portion of the lubricant on an outer periphery of the lubricant applying member due to rotating so as to apply the lubricant to the image carrier; and a solid material that is adjacently provided with the lubricant on an upstream side in a rotation direction of the lubricant applying member, wherein the solid material has a higher level of hardness than the lubricant and is worn out due to contact with the lubricant applying member.

Claims (18)

1. A lubricant applying device, comprising:

an image carrier;

a lubricant;

a lubricant applying member that contacts the image carrier and the lubricant, and maintains a portion of the lubricant on an outer periphery of the lubricant applying member due to rotating so as to apply the lubricant to the image carrier; and

a solid material that is adjacently provided with the lubricant on an upstream side in a rotation direction of the lubricant applying member,

wherein the solid material has a higher level of hardness than the lubricant and is worn out due to contact with the lubricant applying member.

2. The lubricant applying device according to claim 1 , wherein the lubricant is a solid lubricant.

3. The lubricant applying device according to claim 1 , wherein the solid material has a plurality of layers.

4. The lubricant applying device according to claim 1 , wherein the solid material has a hardness distribution such that the hardness of the solid material continuously decreases from the upstream side to the downstream side in the rotation direction of the lubricant applying member.

5. The lubricant applying device according to claim 1 , wherein the lubricant applying member is a brush roller.

6. The lubricant applying device according to claim 1 , wherein a contact surface of the solid material with the lubricant applying member has a shape corresponding to the outer periphery of the lubricant applying member.

7. The lubricant applying device according to claim 1 , wherein the solid material is a lubricant.

8. An image forming apparatus, comprising:

an image carrier;

a development unit that forms an image on the image carrier;

a transfer unit that transfers the image formed by the development unit on a printing medium;

a fixing unit that fixes the image transferred by the transfer unit to the printing medium; and

the lubricant applying device according to claim 1 .
