Abstract
A heating device capable of suppressing electrically conductive parts that electrically connect power supply electrodes and heating resistors from generating heat. The heating device has heating resistors disposed in a longitudinal direction of an elongated base plate and connected through electrically conductive parts to power supply electrodes disposed on one longitudinal end portion of the base plate and supplied with electric power from the power supply electrodes. The electrically conductive parts are formed such that electrically conductive parts that can provide larger amounts of power supply each have a larger cross-sectional area perpendicular to a power supply direction.
