Abstract:
1. A warming-up method for an electrophotography image forming apparatus comprising an image fix-related driving body for rotating a heated roller with a built-in heat source and a pressing roller in contact with the heated roller, and a main driving body for rotating an organic photo conductive (OPC) drum, the method comprising the steps of: heating the rollers by turning on the heat source when the image forming apparatus is turned on or when a wake-up event is generated in power saving mode, and driving the image fix-related driving body for rotating the heated roller and the pressing roller; driving the main driving body and rotating the OPC drum after driving the image fix-related driving body,; and stopping the image fix-related driving body and the main driving body when a surface temperature of the heated roller and the surface temperature of the pressing roller reach an objective temperature, respectively, by means of heat from the heat source and rotation of the heated roller and the pressing roller.
