Abstract

An electrophotographic apparatus is provided with a control device for controlling the heating temperature of the fixing unit in accordance with the detected result by use of a condition detection mechanism. The control device controls the fixing unit: (a) to set the heating temperature thereof to a fixing possible temperature when the condition detection device detects that the imaging operation of the imaging device is initiated or has been continuing, (b) to set the heating temperature to a stand-by temperature lower than the fixing possible temperature when the condition detection device detects that a stand-by condition, in which the imaging operation is interrupted, continues for a first predetermined time, and (c) to set the heating temperature to a save-energy temperature, lower that the stand-by temperature, when the condition detection device detects that the stand-by condition has been continuing for a second predetermined time.
