Abstract

PURPOSE: To automatically stabilize the prooer developing bias voltage to impress it upon a developing section by detecting the maximum level of the light quantity for exposure, which is obtained before the leading end portion of an electrostatic latent image reaches the developing position, to detect the texture density of an original.
