Abstract
An example fuser includes a flexible fixing belt, a backup member to form a fixing nip with the fixing belt, a heater substrate for heating the fixing belt at the fixing nip and having a first surface comprising a heating element pattern, a common terminal and a driving power supply terminal for supplying power to the heating element pattern, and a second surface in contact with the fixing belt, and a temperature sensor sheet comprising a temperature sensor, a sensing terminal and an electric wire connecting the temperature sensor to the sensing terminal, wherein the temperature sensor sheet is in contact with the first surface of the heater substrate such that the sensing terminal and the electrical wire do not overlap the common terminal and the driving power supply terminal.
