Abstract
A fuser heater member for an electrophotographic imaging device, including a heater member. According to an example embodiment, the heater member includes positive temperature coefficient (PTC) material disposed along a width of a fuser nip of the fuser assembly; first and second electrodes disposed along disposed surfaces of the PTC material; an intermediate layer disposed over the second electrode; and at least one resistive trace disposed along the intermediate layer along the width of the fuser nip. The heater member includes a plurality of wire segments coupled to the first and second electrodes and the resistive elements for use in generating heat from at least one of the PTC material and the at least one resistive trace during a fusing operation.
