Abstract: In an image forming apparatus forming an electrostatic latent image on a surface of a photosensitive body by exposing the charged photosensitive body, developing the latent image using a toner to form a toner image, transferring the toner image to a image holding body, and erasing the remaining charge on the surface of the photosensitive body after completion of the transferring, the photosensitive body is formed of a base material consisting of As.sub.2 Se.sub.3 or a-Si, and wherein the wavelength .lambda..sub.0 of the writing light used for the exposure is limited to a wavelength not larger than 780 nm, the wavelength .lambda..sub.1 of charge erasing light used for the charge erasing is limited to a wavelength smaller than 680 nm, and the time T.sub.1 from completion of the exposure to initiation of the development is limited within the range of 70 milliseconds to 300 milliseconds.

Abstract: An image forming method and apparatus creates two toner images on a single portion of an image member. The first toner image formed has multiple density levels. It is recharged before creating the second toner image. An aspect of the potential associated with the toner in the first toner image after the recharge step is monitored and used to control the process, for example, by setting a development bias on a development station used to tone the second toner image or by controlling the recharging step.
