Abstract

An electroluminescence device which has a short light emission decay time and high light emission efficiency and an electronic printing apparatus which can print at a high speed using the electroluminescence device. The electroluminescence device comprises an electroluminescence element for emitting light when an AC voltage is applied thereacross, heating means for heating the electroluminescence element, and controlling means for controlling the heating means so as to start operation of the heating means after completion of application of the AC voltage across the electroluminescence element. The electronic printing apparatus comprises such an electroluminescence device, a photosensitive member, and optical means for focusing light from the electroluminescence element upon the photosensitive member.
