Abstract
In a fixing device for fixing a toner image onto a recording medium, a heating roller is provided with an elastic layer formed on an outer periphery thereof. An endless belt is adapted to be circulated. A press member presses a part of the endless belt against the heating roller so as to deform the elastic layer, thereby forming a fixing nip portion through which the recording medium it passed. A guide member has a slope portion extended so as to close to a tangential line defined at a press contact position between the heating roller and the press member, as is being away from the exit of the fixing nip portion. A fixing pressure generated at the exit of the fixing nip portion is greater than a fixing pressure generated at an entrance of the fixing nip portion.
