Abstract
A heater includes a heater substrate, a first conductor, a second conductor disposed substantially parallel to the first conductor in a longitudinal direction, and at least one heat generator disposed between the first conductor and the second conductor in the transverse direction and configured to electrically connect the first conductor and the second conductor. The at least one heat generator generates heat by energization between the first and second conductors, and a path of a current flowing through the at least one heat generator from one of the first conductor and the second conductor to another conductor has a curved shape.
Claims20
A heater, comprising:
- a heater substrate;
- a first conductor disposed on a surface of the heater substrate along a longitudinal direction thereof;
- a second conductor disposed substantially parallel to the first conductor, with an interval separating the second conductor from the first conductor in a transverse direction;
- and
- at least one heat generator disposed between the first conductor and the second conductor in the transverse direction and configured to electrically connect the first conductor and the second conductor,
- wherein the at least one heat generator is configured to generate heat in response to energization between the first conductor and the second conductor,
- wherein a path of a current flowing through the at least one heat generator from one of the first conductor and the second conductor to another one of the first conductor and the second conductor has a curved shape, and
- wherein an inclination of a tangent of the path continuously changes in a partial region before an intermediate point of the path from the one conductor to the other conductor.
A heater, comprising:
- a heater substrate;
