Method for processing cylinder periphery, processes for producing development roller and photoconductor drum, and development roller and photoconductor drum
First Claim
1. A method for processing cylinder peripheries characterized in that asperities formed on a die are transferred to a metallic glass film formed on the periphery of a cylindrical column-shaped or cylindrical tube-shaped core of a roller by:
- heating the metallic glass film to turn into a viscous fluid; and
rotating or rolling the roller while the metallic glass film is pressed against the die having the asperities.

Abstract
To provide a method for processing cylinder peripheries, capable of highly precise, stable transfer; a process for producing a development roller and a photoconductor drum; and the development roller and the photoconductor drum produced by the process. Asperities formed on a die are transferred to a metallic glass film formed on the periphery of a cylindrical column-shaped or cylindrical tube-shaped core of a roller by: heating the metallic glass film to turn into a viscous fluid; and rotating or rolling the roller while the metallic glass film is pressed against the die having the asperities. The metallic glass film is formed by, for example, thermal-spraying a metallic glass in a liquid state onto the periphery of the core.
