Abstract

A coating apparatus configured to coat a peripheral surface of an endless member with a coating liquid, includes: a holding member configured to hold the endless member; an impregnation member configured to be impregnated with the coating liquid and configured to coat the endless member with the coating liquid in contact with the endless member; a nozzle member configured to eject the coating liquid onto the endless member; a rotating mechanism configured to rotate the holding member relative to the impregnation member and the nozzle member; and a moving mechanism configured to move the holding member relative to the impregnation member and the nozzle member so that the coating liquid is ejected from the nozzle member onto the endless member in a region where the coating liquid is already coated by the impregnation member.

First claim

What is claimed is:

1. A coating apparatus configured to coat a peripheral surface of an endless member with a coating liquid, comprising:
a holding member configured to hold the endless member;
a nozzle member configured to eject the coating liquid onto the endless member;
an impregnation member provided at a position lower than a free end of the nozzle member in a gravitational direction and configured to be impregnated with the coating liquid that is on the endless member, the coating liquid having been ejected from the nozzle member, through contact with the endless member;
a rotating mechanism configured to rotate the holding member relative to the impregnation member and the nozzle member; and
a moving mechanism configured to move the holding member relative to the impregnation member and the nozzle member in a direction substantially opposite to the gravitational direction so that the coating liquid is ejected from the nozzle member onto the endless member in a region where the endless member has already come into contact with the impregnation member.

2. The coating apparatus according to claim 1 , further comprising an executing portion configured to execute a rotating operation by the rotating mechanism and a moving operation by the moving mechanism in parallel when a coating operation by the impregnation member and an ejecting operation by the nozzle member are performed.

3. A fixing member manufacturing apparatus configured to manufacture an endless fixing member including a substrate and a rubber layer provided on the substrate, comprising:
a holding member configured to hold the substrate;
a nozzle member configured to eject an adhesive liquid onto the substrate;
an impregnation member provided at a position lower than a free end of the nozzle member in a gravitational direction and configured to be impregnated with the adhesive liquid that is on the substrate, the adhesive liquid having been ejected from the nozzle member, through contact with the substrate;
a rotating mechanism configured to rotate the holding member relative to the impregnation member and the nozzle member; and
a moving mechanism configured to move the holding member relative to the impregnation member and the nozzle member in a direction substantially opposite to the gravitational direction so that the adhesive liquid is ejected from the nozzle member onto the substrate in a region where the substrate has already come into contact with the impregnation member.

4. The fixing member manufacturing apparatus according to claim 3 , further comprising an executing portion configured to execute a rotating operation by the rotating mechanism and a moving operation by the moving mechanism in parallel when a coating operation by the impregnation member and an ejecting operation by the nozzle member are performed.

5. The fixing member manufacturing apparatus according to claim 3 , further comprising:
a heating mechanism configured to heat the adhesive liquid coated on the substrate;
a coating mechanism configured to coat the rubber layer onto the substrate on which the adhesive liquid is cured by the heating mechanism; and
a heating mechanism configured to heat the rubber layer coated on the substrate.

6. The fixing member manufacturing apparatus according to claim 5 , further comprising a coating apparatus configured to coat the rubber layer with a fluorine containing resin layer via an adhesive layer.

7. The fixing member manufacturing apparatus according to claim 6 , further comprising a heating mechanism configured to heat the fluorine containing resin layer coated on the rubber layer.
