ABSTRACT:
An electrostatic reproducing apparatus wherein a detecting device for toner image density on the charge receptor and an exposure device are provided between the developing device and the charging device, a discharge current of the charging device and/or the quantity of light irradiated onto the charge receptor from the exposure device can be changed according to information from the detecting device. A detecting device for developing current at the time of development is provided in the developing device, a discharge current of the charging device can be changed according to information from the detecting device. A detecting device for a surface potential on the charge receptor after formation of the electrostatic latent image is provided, a discharge current of the charging device can be changed according to an output signal from the detecting means.
