摘要： Disclosed is an image heating apparatus. The image heating apparatus includes a rotatable heating member for heating an image on a recording material in a nip portion, and a heating unit for heating the heating member from the outside thereof. With this structure, a warm-up time period or a first print-out time period can be reduced, and low power consumption can be accomplished. Further, satisfactory image quality can be realized with no heating (fixing) irregularity. The heating member has a low thermal conductive elastic layer, and a heat storage layer outside the low thermal conductive elastic layer to have a volume heat capacity larger than the low thermal conductive elastic layer. A heat capacity of the heat storage layer per unit surface area of a fixing member is in a range of 100 J/m2K to 600 J/m2K.

摘要： An image forming apparatus has sufficient fixing stability and load capacity and being free of sheet jamming and poor image formation. An image forming apparatus includes a transfer voltage applying section for applying a voltage to a transfer section; a transfer current detector for detecting the transfer current flowing through the transfer section; a fixing section for fixing the toner image to fixing position at a predetermined temperature; and a size detector for detecting the size of the recording material. The transfer voltage applying section applies a predetermined transfer voltage, while the recording material passes through the transfer section, so that the transfer current is kept a constant current. When the predetermined transfer voltage is lower than a threshold voltage and the size of the recording material is larger than the predetermined size, the fixing section fixes the toner image at a temperature which is lower than the predetermined temperature.
