Heater for use in electrophotographic image fixing device

摘要

A ceramic heater for use in an electrophotographic printing process, particularly for use with a belt fuser to fix toner images, is disclosed. This heater is preferably made from a ceramic material substrate and contains a heat-generating resistor and electrical connections for said resistor on one face of the substrate and a temperature-detecting element for detecting and controlling the temperature of said heater, together with electrical connections for said detecting element, on the opposing face of the substrate. Belt fusers, which incorporate these heaters, are also disclosed.
