Abstract:
1. A developing roller comprising a shaft, an elastic layer formed on the outer periphery of the shaft and at least one resin coating layer formed on the outer peripheral surface of the elastic layer, wherein the resin coating layer comprises at least one selected from the group consisting of an ultraviolet non-curable fluorine-containing resin, an ultraviolet non-curable fluorine-containing compound, an ultraviolet non-curable silicon-containing resin and an ultraviolet non-curable silicon-containing compound, and an ultraviolet-curing type resin, and the resin coating layer is formed by applying a coating liquid comprising at least one selected from the group consisting of the ultraviolet non-curable fluorine-containing resin and compound and silicon-containing resin and compound, and a resin and/or compound having an ultraviolet polymerizable carbon-carbon double bond but not containing fluorine and silicon on the outer peripheral surface of the elastic layer and then curing the resin and/or compound having the ultraviolet polymerizable carbon-carbon double bond but not containing fluorine and silicon by ultraviolet irradiation.
