Fuser and image forming apparatus to transmit different types of signals from fuser to image forming apparatus via common terminal

Abstract

A fuser configured to be removably attached to an image forming apparatus includes a heating rotatable body for heating a sheet, a heater for heating the heating rotatable body, a pressure rotatable body for nipping the sheet between the pressure rotatable body and the heating rotatable body, a temperature sensor for detecting a temperature of the heating rotatable body, a state detection sensor for detecting a state of the fuser, a fuser connector configured to be connected to a main body connector of the image forming apparatus when the fuser is attached to the image forming apparatus, and a relay board including a common terminal connected to the fuser connector. The relay board is connected to the temperature sensor and the state detection sensor and is configured to transmit respective signals output from the temperature sensor and the state detection sensor to the image forming apparatus via the common terminal.
