    摘要： An exposure device having an array of a plurality of light emitting elements composed of at least an anode layer, a cathode layer and one or more organic compound layers interposed between the anode layer and the cathode layer all of which are formed on a substrate. In the exposure device, the quantity of light emitted from each light emitting element is made uniform by controlling the light emitting area of each light emitting element. Therefore, the exposure device eliminates differences in the quantity of emitted light among the plurality of light emitting elements without using a special drive circuit.

    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.

    摘要： An image forming apparatus capable of enhancing the accuracy of the scanning position of a laser beam to thereby obtain a more precise image. Optical sensors detect reflected light from a surface of a photosensitive drum. During image formation, the apparatus detects the scanning speed of the laser beam in a main scanning direction based on detection signals from the respective optical sensors in each of divisional sections of an image forming area in the main scanning direction. The apparatus corrects magnification of the image in the main scanning direction, based on results of detection of the scanning speed of the laser beam in the main scanning direction.
