Abstract
A fixing device for fixing on a recording material a toner image formed on the recording material includes: a flexible sleeve including a resinous base layer, a parting layer, and an adhesive layer for bonding the base and parting layers; a heater contacting the sleeve; a pressor for forming a nip with the sleeve, in which the recording material is nipped and conveyed; a member for applying a voltage, with the same polarity as toner; and a grounder contacting the recording material in the nip, for grounding the recording material. In a thickness direction of the layers, the electric resistance of the adhesive layer is larger than that of the parting layer, which is larger than that of the base layer. The member applies the voltage to the sleeve in contact with the base layer.
