Heating apparatus

Abstract

A heating apparatus may include a plurality of heaters each extending in a first direction, in which the heaters are arranged in a second direction perpendicular to the first direction; a housing section that houses the plurality of heaters; a supply passage that extends in the first direction above the housing section, in which a heat medium to be supplied to the housing section flows through the supply passage; and a supply opening that communicates the supply passage with the housing section and extends in the first direction. The supply passage may include a narrowed portion extending in a direction from an inlet of the supply passage toward a downstream side. A flow cross-sectional area of the narrowed portion may decrease in the direction from the inlet of the supply passage toward the downstream side.
