Abstract:
A heating unit includes a circuit board, a plurality of heating parts, and a plurality of wiring parts. The heating parts are arranged in a first direction on a surface of the circuit board. The wiring parts are provided on the surface of the circuit board and electrically connect the heating parts and a power source to feed the heating parts. The wiring parts respectively include electrode terminal parts electrically connected to the power source outside the heating parts in the first direction. Sizes in a second direction orthogonal to the first direction of the heating parts are set to decrease gradually or stepwisely with separating in the first direction from the electrode terminal parts.

Claim (Index 7):
A fixing device comprising:\n a fixing member configured to heat toner on a medium with rotating around an axis thereof; a pressing member configured to, with rotating around an axis thereof, form a pressing area with the fixing member and press the toner on the medium passing through the pressing area; and a heating unit configured to be provided opposite to the pressing member across the fixing member and heat the fixing member, wherein a diameter of the pressing member is set to decrease gradually from both ends in an axial direction toward a center, the heating unit including: a circuit board; a plurality of heating parts provided to be arranged in the axial direction of the fixing member on a surface of the circuit board; and a plurality of wiring parts provided on the surface of the circuit board and electrically connecting the heating parts and a power source to feed the heating parts, wherein the wiring parts respectively include electrode terminal parts electrically connected to the power source outside the heating parts in the axial direction, wherein sizes in a passing direction orthogonal to the axial direction of the heating parts are set to decrease gradually or stepwisely from both ends in the axial direction toward a center in the axial direction, and wherein a size in the passing direction of a heating part located at another end in the axial direction is set to be smaller than a size in the passing direction of a heating part located at one end in the axial direction.
