Abstract:
1. A heater comprising: an elongate substrate; a first conductor provided on the substrate along a longitudinal direction of the substrate; a second conductor provided on the substrate along the longitudinal direction of the substrate at a position different from a position of the first conductor in a lateral direction of the substrate; and a plurality of heat generating resistors connected in parallel between the first conductor and the second conductor, and configured to generate heat by electrical power supplied through the first and second conductors, wherein a temperature coefficient of resistance of the plurality of heat generating resistors is negative, wherein each of the plurality of heat generating resistors overlaps an adjacent heat generating resistor in the longitudinal direction of the substrate, wherein each of the first conductor and the second conductor includes: a first side parallel with the longitudinal direction of the substrate, a second side including triangular shaped regions, wherein the second side of the first conductor and the second side of the second conductor are opposed to each other, and wherein each of the plurality of heat generating resistors is connected at one of the triangular shaped regions in the second side of the first conductor and at one of the triangular shaped regions in the second side of the second conductor.
