Abstract: A heating unit includes a cylinder which rotates about an axis parallel to a first direction. A heater has a first surface abutting on an inner surface of the cylinder at a nip position. A support member is on a second surface of the heater and also contacts the cylinder. A first heating element is in the heater at a first position along the first direction. A second heating element in the heater is at a second position spaced from the first position. A first temperature sensor is above the first position. A locking portion of the heater is at a third position along the first direction. The locking portion engages the support member and restricts movement of the heater in the first direction. The first position is near a first outer edge of the cylinder. The second position is closer to a central portion of the cylinder.

Abstract: A heating unit includes a rotating cylinder rotating about an axis parallel to a first direction. A heater having a width in a second direction is on the inner surface of the cylinder. A support member holds the heater fixed relative to the cylinder and includes an upstream member adjacent to the heater in the second direction and a downstream member adjacent to the heater in the second direction. The heating unit may include, in some examples, a stay supporting the support member, a guide member on the stay, and a temperature sensor to measure a temperature of an inner surface of the cylinder.

Abstract: An image processing apparatus includes a fixing unit including a heater and a fixing belt. The fixing belt is electrically connected between a first power source and a ground terminal. A controller is configured to control the heater to heat the fixing belt. The controller is further configured to determine whether a current is flowing through the fixing belt and, upon determining that a current is not flowing through the fixing belt, control the heater not to heat the fixing belt.
