Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
