Abstract
A heater includes a substrate, a first electrical contact, a plurality of second electrical contacts, a plurality of electrode portions including first electrode portions electrically connected with the first electrical contact and second electrode portions electrically connected with the second electrical contacts, the first electrode portions and the second electrode portions being arranged alternately with predetermined gaps in a longitudinal direction of the substrate, and a plurality of heat generating portions provided between adjacent ones of the electrode portions so as to electrically connect between adjacent electrode portion. The heat generating portions are capable of generating heat by the electric power supply between adjacent electrode portions. A part of the second electrical contacts is selectably electrically connectable with the second terminal. The electrode portions are covered with the heat generating portions so as to be positioned between the substrate and the heat generating portions.
