An electrophotographic device constructed with a light irradiating device to irradiate light on a photosensitive member, a charging device to uniformly charge the photosensitive member after the light irradiation by the light irradiating device; a light image projecting device to project a light image after the charging by the charging device to thereby form an electrostatic latent image corresponding to the light image on the photosensitive member, a developing device to develop the electrostatic latent image, and a control device to vary the irradiated light quantity by the light irradiating device and the exposure light quantity by the light image projecting device in accordance with a potential state of the photosensitive member at the time of the latent image formation.
An electrophotographic device, comprising:
The electrophotographic device according to claim 2 or 17, wherein said time constant circuit further counts the stoppage time of the device, and adjusts said irradiated light quantity and said exposure light quantity in accordance with lapse of said lighting time and said stoppage time.
