Rotating body for image forming apparatus

Abstract

A rotating body for an image forming apparatus is provided having a substrate; and a covering layer adhered to the surface of the substrate, the surface being subjected to activation by silicifying it with flame. The rotating body of present invention can exhibit excellent adhesiveness between the substrate and the covering layer, even if primer treatment is not carried out on the surface of the substrate.

Description

field of invention [0001] The present invention relates to rotating bodies used in image forming apparatuses such as copiers, printers and facsimiles. Background technique [0002] A rotating body used in an image forming apparatus such as a roller, an endless belt or a sleeve is prepared by forming a primer layer on the surface of a substrate made of materials such as metal, ceramics, etc. to improve adhesion made of inorganic materials or organic materials such as synthetic polymer resins; and then coated with covering layers such as elastic layers or release layers, which are disclosed in Japanese Patent Laid-Open No. 2002-337161, for example. [0003] However, several problems arise when primer treatments are applied to improve adhesion. Specifically, a problem arises when a primer layer is formed on the surface of a substrate made of metal or an organic material such as a synthetic polymeric resin. When these materials are used as substrates, steps of baking and cooli...

Problems solved by technology

However, since such plating can only be performed on the substrate before the covering layer is formed thereon, there is no effective masking method to ensure that the part to be coated is not plated with nickel, and a method has been proposed which includes the following steps: plating with nickel Coating the entire surface of the mandrel and then selectively removing the resulting nickel plating from the portion on which the coating is to be covered by methods such as abrasion, but this method is time-consuming

[0006] Another problem is that when the reagents used for primer treatment include solvent as one of its components, 1) the solvent should be dried in an oven for a short period of time, which requires high investment in facility costs and high operating costs, 2) the solvent and its Vapors should be removed, purified and / or treated by additional work-up methods, and 3) the possibility of contaminating the surrounding air should be eliminated when drying the solvent

[0007] As mentioned above, conventional primer treatment should be carried out in multiple stages, resulting in high investment and high operating costs requiring facility costs
