Abstract
The heater is capable of improving heat generation uniformity in a sheet feeding area while suppressing the temperature rise of a non-sheet feeding portion. Each of heat generation lines includes a plurality of heat blocks in which a plurality of heat generating resistors are electrically connected in parallel between two conductive members. The heat generation lines are arranged in a lateral direction of the substrate, and the heat blocks are arranged so that the end of the heat block in the heat generation line of a first row does not overlap with the end of the heat block in the heat generation line of a second row in a longitudinal direction of a heater.
