Abstract:
A fixing device, comprising:a fixing member; a pressing member mounted to be in press-contact with said fixing member, wherein said fixing member and said pressing member are rotatable to sandwich a recording material bearing a toner image therebetween, to thereby fix the toner image onto the recording material by heat and pressure; a primary temperature detector positioned and configured to detect a temperature of said fixing member; a primary heater positioned and configured to heat said fixing member, wherein energization of said primary heater is controlled such that the temperature of said fixing member reaches a target temperature suitable for fixing the toner image based on a detection result of said primary temperature detector; and a controller adapted and connected to control at least said primary heater and the rotation of said fixing member and said pressing member such that at a startup of the fixing device occurs at a startup temperature of said fixing member that is higher than the target temperature, and a rotation of said fixing and pressing members is controlled such that said fixing and pressing members start a pre-rotation when said primary temperature detector detects that the temperature of the fixing member reaches the startup temperature.
