Abstract
The present invention provides a lubricant coater including an applying member for applying a lubricant powder on a surface of an image bearing member, wherein the lubricant powder contains paraffin as a main component, and the lubricant coatability of the applying member is controlled such that a maximum thickness of a lubricant film formed on the image bearing member, which is obtained after the lubricant powder is continuously applied on the surface of the image bearing member for 120 minutes, is 0.25 μm or less.
Claims6
A lubricant coater comprising:
- an applying member for applying a lubricant powder on a surface of an image bearing member,
- wherein the lubricant powder comprises paraffin as a main component, and
- wherein the lubricant coatability of the applying member is controlled such that a maximum thickness of a lubricant film formed on the image bearing member, which is obtained after the lubricant powder is continuously applied on the surface of the image bearing member for 120 minutes, is 0.25 μm or less.
An image bearing unit comprising:
- an image bearing member for supporting a toner image on its surface, and
- a lubricant applying unit configured to apply a lubricant on the surface of the image bearing member,
- wherein the lubricant powder comprises paraffin as a main component, and
- wherein the lubricant coatability of the applying member is controlled such that a maximum thickness of a lubricant film formed on the image bearing member, which is obtained after the lubricant powder is continuously applied on the surface of the image bearing member for 120 minutes, is 0.25 μm or less.
An image forming apparatus, comprising:
- an image bearing unit which comprises:
- an image bearing member for supporting a toner image on its surface, and
- a lubricant applying unit configured to apply a lubricant on the surface of the image bearing member, and
- an image forming unit configured to form a toner image on the surface of the image bearing member,
- wherein the lubricant powder comprises paraffin as a main component, and
- wherein the lubricant coatability of the applying member is controlled such that a maximum thickness of a lubricant film formed on the image bearing member, which is obtained after the lubricant powder is continuously applied on the surface of the image bearing member for 120 minutes, is 0.25 μm or less.
An image forming apparatus comprising:
- an image bearing member for supporting a toner image on its surface,
- a lubricant applying unit configured to apply a lubricant on the surface of the image bearing member, and
- an image forming unit configured to form a toner image on the surface of the image bearing member,
- wherein the lubricant coatability of the applying member is controlled such that a maximum thickness of a lubricant film formed on the image bearing member, which is obtained after the lubricant powder is continuously applied on the surface of the image bearing member for 120 minutes, is 0.25 μm or less.
