Abstract

PURPOSE: To make possible controlling of the development of the latent images following to the electrostatic latent images and perform stable image formation by projecting the specified quantity of light to the non-image parts between the continuous latent images to form the electrostatic latent images and measuring the potentials of the electrostatic latent images.
CONSTITUTION: When a copying start signal is inputted from a key input means 208, a CPU 201 emits a motor drive signal MD and this causes a high voltage AC destaticizer 23, high voltage primary charger 22, full surface radiating lamp 24, blank exposure lamp 10 and sensor motor to go ON, whereby the forward revolution is accomplished. The AC signal detected with an electrometer 50 is DC-reproduced 205 and this voltage is stored 206. Upon ending of the forward revolution, the exposure lamp 16 lights up and developing is accomplished. During copying and optical system backward moving, the blank light is radiated and the bright part potentials are measured and stored, thus controlling of a developing bais control circuit 207 is accomplished in the similar manner.
