The heater includes a substrate made of metal. The fixing unit further includes a power supply connector electrically connected to the power supply electrode so that the power supply connector is connected to the heating element at a first end portion of the substrate in a longitudinal direction of the heater, and a pressing member opposed to the nip forming unit. The fixing unit further includes a voltage application circuit configured to apply a voltage of a same polarity as a normal charging polarity of the toner to the substrate, the voltage application circuit being connected to the substrate at a second end portion of the substrate opposite to the first end portion in the longitudinal direction.
