Patent ID: 8532554

Claim:
A fixing device for fixing on a recording material a toner image formed on the recording material, said fixing device comprising: a flexible sleeve including a resinous base layer, a parting layer and an adhesive layer bonding the base layer and the parting layer; a heater contacting an inner surface of said sleeve; a pressing member configured to form a nip, in which the recording material on which the toner image has been formed is nipped and conveyed, between itself and said sleeve which said heater contacts; a voltage applying member configured to apply a voltage, of a polarity identical to a polarity of toner; and a grounding member, contactable to the recording material in a nipped state in the nip, configured to ground the recording material, wherein in the base layer, an electroconductive filler is dispersed, wherein in a thickness direction of the layers, the electric resistance of the adhesive layer is larger than that of the parting layer and the electric resistance of the parting layer is larger than that of the base layer, and wherein said voltage applying member applies the voltage to said sleeve in contact with the base layer.
