Abstract
A heating device includes a roller and a pressure member. The roller includes a base body, a thermal capacitor, and a heater. The base body extends from a center portion to each end portions of the roller in a longitudinal direction of the roller. The thermal capacitor is disposed on each of the end portions of the roller. The thermal capacitor has a larger thermal capacity than the base body. The heater is disposed inside the base body to heat the base body. The pressure member faces the roller to press a recording medium against the roller.
