Abstract

A light emitting component includes: a substrate; an array-like light source unit that is provided at the substrate and in which multiple light emitting elements are arranged in a first scanning direction; a controller that is provided at the substrate and that controls an electric current to turn on and off each light emitting element of the light source unit; a resistor that is provided at the substrate and alongside an end of the light source unit in the first scanning direction, the resistor limiting the electric current supplied to each light emitting element; and a heat generator that is provided at the substrate and at a position located parallel to the first scanning direction of the light source unit and located away from the resistor, the heat generator generating a heat quantity that is smaller than a heat value dependent on electric power input to the resistor and that is proportional to the heat value.
