Abstract
A lubricant applying unit includes a lubricant applying member, and a leveling member for use in an image forming apparatus having a photosensitive member. The lubricant applying member applies lubricant on a surface of the photosensitive member, and the leveling member levels off the lubricant on the surface of the photosensitive member. The lubricant applying unit applies the lubricant with a predetermined amount on the surface of the photosensitive member. The photosensitive member includes polyarylate resin in a surface layer of the photosensitive member.
Claims32
A lubricant applying unit for use in an image forming apparatus having a photosensitive member and a charge device, comprising:
- a lubricant applying member configured to apply lubricant on a surface of the photosensitive member;
- and
- a leveling member configured to level off the lubricant applied on the surface of the photosensitive member,
- wherein the lubricant applying unit applies the lubricant in an amount of 1.2×10−7 g/cm2 to 1.3×10−6 g/cm2 per unit area of the photosensitive member.
A lubricant applying unit for use in an image forming apparatus having a photosensitive member and a charge device, comprising:
- means for applying lubricant on a surface of the photosensitive member;
- and
- means for leveling off the lubricant on the surface of the photosensitive member,
- wherein the lubricant applying unit applies the lubricant in an amount of 1.2×10−7 g/cm2 to 1.3×10−6 g/cm2 per unit area on the surface of the photosensitive member.
An image forming apparatus, comprising:
- at least one photosensitive member;
- a charge device configured to apply a bias voltage to the photosensitive member;
- a lubricant applying member configured to apply lubricant on a surface of the photosensitive member;
- and
- a leveling member configured to level off the lubricant on the surface of the photosensitive member,
- wherein the lubricant applying member applies the lubricant in an amount of 1.2×10−7 g/cm2 to 1.3×10−6 g/cm2per unit area on the surface of the photosensitive member.
