METHOD FOR PRODUCING ROLLER FOR OFFICE AUTOMATION EQUIPMENT AND ROLLER FOR OFFICE AUTOMATION EQUIPMENT

摘要

Provided are a method for producing a roller for office automation (OA) equipment, the roller capable of realizing an increase in the printing speed and having a good releasing property, and a roller for OA equipment. The method for producing a roller for OA equipment, the roller including a fluororesin layer provided on an outer circumferential surface of a tubular base either directly or with an intermediate layer therebetween, includes the steps of preparing a fluororesin coating material containing a tetrafluoroethylene-perfluoroalkylvinylether copolymer (PFA) and polytetrafluoroethylene (PTFE) in a ratio of 99:1 to 50:50 (mass ratio); applying the fluororesin coating material onto an outer circumferential surface of a tubular base either directly or with an intermediate layer therebetween; baking the fluororesin coating material at a temperature of 340° C. or higher to form a fluororesin layer; and after baking, cooling the fluororesin layer at a cooling rate of 20° C./min or less.
