image forming device

Abstract

Abstract PURPOSE:To always form a distinct image having a specified line width even if the operating condition or the environmental atmosphere of the tilt device is changed by correcting the control of an exposing device so that the line width of a developed image may be a reference line width previously set based on the line width detected by a line width detection means. CONSTITUTION:A laser diode 10 constituting the exposing device 3 is connected to the output terminal of a driving device 16 and, on the other hand, a DA converter 17 is connected to the output terminal of a controller 18, then the input terminal of the driving device 16 is connected to the output terminal of the DA converter 17. The deterioration of ozone and the change of the particle diameter of toner which occur in operation or the line width of the developed image which is varied with the change of environmental temperature of the device are detected by a reflection type photosensor 11 and an arithmetic device 13. Then, the laser diode 10 is driven to be corrected by the driving device 16 so that the line width may be the reference line width previously set. Thus, the image having the specified line width can always be formed even if the operating condition or the environmental atmosphere is changed.
