PURPOSE:To manufacture an electrostatic recording device at low cost with high productivity by making the constitution of the electrostatic recording which mounts a photosensitive body of different kind almost common except the photosensitive body. CONSTITUTION:A CPU read data on the mounted photosensitive body 1 out of a memory stored with data on the discharge condition of corona dischargers 2 suitable to various photosensitive bodies to be mounted, the light emission condition of an image exposure lamp 4, etc. Then, a high voltage generation 14 is controlled through a digital-analog converter D/A 1 based on the data to control the discharging voltage or current of the corona discharger 2 to a specific value. Further, the light emitting circuit which includes a photocoupler 15, a triac 16, a diode AC switch 17, etc., is controlled through a digital-analog converter D/A 2 to control the quantity of light emission of the image exposure lamp 5 to a specific value. The discharge condition of the corona discharger 2, the light emission condition of the image exposure lamp 5, etc., which are set by the CPU based on the data from the memory are reference condition for reproducing original image density, etc., faithfully, and the reference condition is altered when the image density, etc., are varied by preference. |
