摘要： A heating apparatus includes a cylindrical film and a pressing element that rotates with the cylindrical film and forms a nip with the cylindrical film. A medium is conveyed through the nip from an upstream side to a downstream side. The heating apparatus further includes a heater arranged inside the cylindrical film and on which a heating element is disposed. An upstream end of the heater is located downstream of an upstream end of the nip, and a downstream end of the heater is located downstream of a downstream end of the nip.

摘要： A heater is to face a pressure element via a belt and is to heat the belt. The pressure element sandwiches and conveys a sheet together with the belt. The heater includes a substrate, a heat generating element, and a protective layer. The heat generating element is on the substrate. The protective layer covers the heat generating element and the substrate and whose surface is concave with respect to the pressure element. In the protective layer, a curvature of a top surface of an upstream end in a conveyance direction of the sheet is smaller than a curvature of a top surface of a downstream end in the conveyance direction.

摘要： A fixing device includes a belt, a roller, a heater, and a reflector. The belt is rotatable in a rotational direction. The roller is positioned to be in contact with an outer peripheral surface of the belt so as to form a nip between the roller and the belt. The heater is disposed within an inner circumference of the belt. The reflector is configured to reflect heat generated by the heater toward an inner surface of the belt. The reflector includes a first portion that is in contact with the belt at a first region downstream with respect to the nip in the rotational direction. The first portion causes a curvature of the belt at the first region to be greater than the curvature of the belt at regions of the belt adjacent to the first region.

摘要： 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.
