Claim:
1. A heating device comprising: a plurality of heat generators that generate heat upon receiving power from a power source; and a substrate including a conductor pattern arranged so as to serially connect the plurality of heat generators to thereby supply the power from the power source to each of the heat generators, wherein the conductor pattern includes a plurality of first conductor elements constituting a forward path from the power source and a second conductor element constituting a backward path from the power source, and each of the plurality of first conductor elements are wider than the second conductor element; the plurality of first conductor elements constitute two rows of conductor patterns by being aligned at equal intervals on the substrate, one of the two rows being arranged in an orthogonal direction to the aligned direction of the other row; among the plurality of first conductor elements, the first conductor elements aligned in the orthogonal direction are connected to each other via the heat generators, thereby serially connecting the heat generators to each other, and a single conductor pattern constituting the forward path is formed to thereby supply the power from the power source to each of the heat generators; and the second conductor element is not connected to the heat generators.
