摘要： A fixing unit for use in an image forming apparatus includes a fixing member, a heating source, and a controller. The fixing member is supported rotatably. The heating source heats the fixing member. The controller controls power supply to the heating source. The controller controls a first average power supply, supplied to the heating source before rotating the fixing member, to be larger than a second average power supply, supplied to the heating source after rotating the fixing member.

摘要： A belt fixing unit, an image forming apparatus, and a toner material are disclosed capable of obviating undesirable fixing belt deformation and low image quality. The belt fixing unit includes a fixing roller, a heating roller, a fixing belt, and a pressing roller in contact with the fixing roller to form a fixing nip having the fixing belt intervening there between, the fixing belt including at least a base member formed of a heat-resisting resin having a thickness of 90 μm or smaller and acted upon by a tensile force of 0.49 N/mm or less. The toner is a low-melting point toner formed by subjecting a toner preparatory solution containing at least a prepolymer having a functional group containing a nitrogen atom, a polyester, a colorant and a releasing agent dispersed in an organic solvent to extension and/or crosslinking reactions in an aqueous medium.

摘要： In a fixing device, a pressing member rotates in a predetermined direction of rotation. A flexible fixing member is disposed opposite the pressing member to rotate in accordance with rotation of the pressing member. A nip formation member is provided inside a loop formed by the fixing member and pressed against the pressing member via the fixing member to form a nip between the fixing member and the pressing member through which a recording medium bearing a toner image passes. A contact member pressingly contacts an outer circumferential surface of the rotating fixing member at both ends of the fixing member in an axial direction thereof.
