Abstract

The image forming method is executed by projecting a light image on a rotatable recording member to consecutively form electrostatic latent images corresponding to the light image, developing the latent images, projecting a predetermined amount of light onto a non-imaged area present between two consecutive latent images on the recording member to form an electrostatic image, detecting potential of the electrostatic image, and controlling the development of the latent images next to the electrostatic image detected during the detection of the potential in response to the detection results. This method is performed in the image forming apparatus which includes a rotatable recording member, processing units for projecting a light image onto the recording member to consecutively form electrostatic latent images corresponding to the light image, a developer unit for developing the latent images, a voltage applying circuit for applying a voltage to the developer unit, a projecting unit for projecting a predetermined amount of light onto a non-imaged area present between two consecutive latent images on the recording member, a detector for detecting surface potential of the non-imaged ar…
