Abstract

The present invention provides a paint film forming apparatus for moving an object to be painted at a certain speed and keeping the gap between the outer periphery face of the object to be painted and the paint nozzle, a photographic fixing component for electrically-imaging and an image forming apparatus, wherein the paint film forming apparatus comprises a keeping portion for keeping a substrate, a paint nozzle (19) for painting the paint on the outer peripheral face (4c) of the substrate (4), and a moving keeping supporting portion (26) for moving the paint nozzle (19), the keeping portion (18) comprises a mandrel passing through the inner side of the substrate (4), and the upper end portion of the mandrel (25) is provided with an exhaust nozzle (28) exhausting air towards the inner peripheral face of the substrate (4). The paint slit (19b) for exhausting paint (7) in the paint nozzle is arranged at a position opposite to the upper end portion of the mandrel (25).

Description

technical field [0001] The present invention relates to a coating film forming device that forms a coating film after applying a coating to the cylindrical outer peripheral surface of an object to be coated, for example, in a PPC (plain paper copier), LBP (laser printer), facsimile machine, etc. In an electrophotographic image forming apparatus, a coating film forming apparatus is preferably used to form an elastic layer of a fixing member (fixing belt, fixing roller) that fixes an unfixed toner image on recording paper by heating and pressing. At the same time, it also relates to a fixing member for electrophotography on which a coating film is formed by the coating film forming apparatus, and an image forming apparatus having the fixing member for electrophotography. Background technique [0002] In image forming apparatuses such as copiers and printers based on the principle of electrophotography, after the recording paper on which the toner image has been transferred is ...
