A process for producing a fixing roller comprising coating a fluorine resin dispersion onto a core by using a transfer coating apparatus comprising a transfer roller equipped with a fluorine resin dispersion temperature controller, a coating pan containing a fluorine resin dispersion, a driving system for revolving the core, and a core carrying mechanism for shifting the core, in which the core is brought close to the transfer roller at a gap allowing the core to pick up the fluorine resin dispersion having been picked up from the coating pan onto the transfer roller, and after a prescribed amount of the fluorine resin dispersion is transferred onto the core, the gap between the core and the transfer roller is widened by shifting the core away from the transfer roller thereby to separate the core from the transfer roller, the coating apparatus further comprising a thin plate on both sides of the transfer roller for preventing the fluorine resin dispersion in contact with both ends of an effective coating width of the core from migrating to the inside of the effective coating width while the gap is widened.
A process for producing a fixing roller comprising coating a fluorine resin dispersion onto a cylindrical core by using a transfer coating apparatus comprising a transfer roller having an axial width equipped with a fluorine resin dispersion temperature controller, a coating pan containing a fluorine resin dispersion, a driving system for revolving the core, and a core carrying mechanism for shifting the core, comprising the steps of bringing said core close to said transfer roller at a gap allowing said core to pick up said fluorine resin dispersion, the fluorine resin dispersion having been picked up from the coating pan by said transfer roller across its entire axial width and after an amount of the fluorine resin dispersion is transferred onto the core, widening said gap between the core and the transfer roller by shifting the core away from the transfer roller to thereby separate the core from the transfer roller,
