摘要： Provided is a light emitting apparatus capable of preventing light emitting elements made of an organic compound from being affected by moisture in an ambience, thereby increasing their lifetime, and suitably applicable to an exposure section of the electrophotographic method. Temperature sensors are set next to a light emitter array which is an array of many light emitting elements made of the organic compound. A drive control unit of the array is composed of CPU, ROM, RAM, and I/O ports. The CPU carries out control of each unit according to input data of image information etc. and also carries out pre-heat control for the light emitting elements. The temperature sensors detect the temperature of the light emitting elements and the CPU, receiving their detection output, turns the light emitting elements or a heating element provided separately, on and off so that a detected temperature value becomes a predetermined value in a waiting state without the input data. In the waiting state the light emitting elements generate heat per se to be kept at the predetermined temperature.
