Abstract
A heater includes a substrate, electrode portions, electrical contact portions, heat generating portions, and electroconductive line portions. The electrode portions include first group electrode portions and second group electrode portions. The electroconductive line portions include a main line portion extending from the electrical contact portions in the longitudinal direction, a first branch line portion branching from the main line portion so as to electrically connect with a first electrode portion of the first group electrode portions, and a second branch line portion branching from the main line portion so as to electrically connect with a second electrode portion of the first group electrode portions. The second electrode portion is spaced farther from the electrical contact portions than the first electrode portion in the longitudinal direction, and the electric resistance of the first branch line portion is larger than the electric resistance of the second branch line portion.
