Abstract
A solid lubricant containing a fatty acid metal salt and a polyethylene having an acid value is prepared. The solid lubricant is disposed so as to be applied on a surface of an image bearing member of an image forming apparatus in electrophotography, and a lubricant layer is formed on the surface of the image bearing member with the solid lubricant.
Claims8
An image forming apparatus comprising:
- a rotatable image bearing member;
- a charging device for charging the image bearing member;
- a transfer device for transferring a toner image born on the charged image bearing member to a toner receiving article;
- and
- a lubricant applying device for applying a lubricant on a surface of the image bearing member, the lubricant applying device being disposed between the transfer device and the charging device in a rotational direction of the image bearing member, wherein
- the lubricant applying device comprises:
- a solid lubricant comprising a fatty acid metal salt, and a polyethylene having an acid value;
- a lubricant applying member that has flexibility and is to be disposed so as to abut freely on the surface of the image bearing member;
- and
- a lubricant supplying device for supplying the solid lubricant to the lubricant applying member.

An image forming method comprising:
- charging an image bearing member;
- forming an electrostatic latent image on a charged image bearing member;
- supplying a toner onto the image bearing member having an electrostatic latent image formed thereon, thereby allowing to bear the toner image on the image bearing member;
- transferring the toner image born on the image bearing member to a toner receiving article;
- and
- applying, on the surface of the image bearing member after transferring the toner image, a lubricant supplied from a solid lubricant, thereby forming a lubricant layer, wherein
- the solid lubricant comprising a fatty acid metal salt, and a polyethylene having an acid value, is used as the solid lubricant.
