Abstract
PURPOSE:To always and properly adjust the density of an image by providing a temperature and humidity measuring apparatus and controlling image forming conditions according to the measured result. CONSTITUTION:The temperature and humidity measuring apparatus 8 which measures temperature and humidity around a developing device 6 by the detecting signal of a temperature and humidity sensor 8a is provided as the detecting means of atmosphere conditions in the main body of a device. The control target value of the surface potential of a photosensitive body 1 is selected according to the atmosphere conditions in the device and image forming is performed based on the target value by means of a target value. Thus, the density of the image can be always and properly adjusted, thereby obtaining high quality images.
