Abstract
A lubricant application device including a solid lubricant, a brush, and a first lubricant scattering prevention member. The solid lubricant is in a non-contact state with a rotating member and provided below a horizontal line of an axis of the rotating member. The brush rotates and contacts both the solid lubricant and the rotating member. The first lubricant scattering prevention member is provided downstream from a first contact position at which the brush contacts the solid lubricant and upstream from a second contact position at which the brush contacts the rotating member in a direction of rotation of the brush.
Claims19
A lubricant application device, comprising:
- a solid lubricant configured to be in a non-contact state with a rotating member and provided below a horizontal line of an axis of the rotating member;
- a brush configured to rotate and contact both the solid lubricant and the rotating member;
- and
- a first lubricant scattering prevention member provided downstream from a first contact position at which the brush contacts the solid lubricant and upstream from a second contact position at which the brush contacts the rotating member in a direction of rotation of the brush.
A process cartridge, comprising:
- an image carrier configured to carry an image;
- and
- a lubricant application device configured to apply a lubricant to the image carrier, the lubricant application device comprising:
- a solid lubricant configured to be in a non-contact state with the image carrier and provided below a horizontal line of an axis of the image carrier;
- a brush configured to rotate and contact both the solid lubricant and the image carrier;
- and
- a first lubricant scattering prevention member provided downstream from a first contact position at which the brush contacts the solid lubricant and upstream from a second contact position at which the brush contacts the image carrier in a direction of rotation of the brush.
An image forming apparatus, comprising:
- an image carrier configured to carry an image;
- and
- a lubricant application device configured to apply a lubricant to the image carrier, the lubricant application device comprising:
- a solid lubricant configured to be in a non-contact state with the image carrier and provided below a horizontal line of an axis of the image carrier;
- a brush configured to rotate and contact both the solid lubricant and the image carrier;
- and
- a first lubricant scattering prevention member provided downstream from a first contact position at which the brush contacts the solid lubricant and upstream from a second contact position at which the brush contacts the image carrier in a direction of rotation of the brush.
