摘要： An image forming apparatus wherein a photosensitive layer arranged to rotate in one direction is charged by a charger, and a negative electrostatic latent image is formed thereon by an exposure unit and then is subjected to reversal development by a developing device so that a positive noticeable image can be attained. The apparatus has a scorotoron charger for charging the negative latent image which has just been formed by the exposure unit with the opposite polarity thereof. A grid of the scorotoron charger is constituted to be impressed with a voltage with the same polarity as the latent image and a value lower than that of the surface potential, and by the scorotoron charger, the potential of the non-imaged portions of the latent image is lowered around the grid voltage. Further, the developing device is constituted to be impressed with a developing bias voltage with the same polarity as the latent image and a value lower than that of the surface potential but higher than a developing threshold value, whereby toner charged with the same polarity as that charged by the charger sticks to the imaged portions with potential lower than the developing bias voltage, resulting in a positive toner image with sharp line widths.

摘要： A method for forming an outline of an image. By this method, at first, an electrostatic latent image bearing member is charged and then irradiated to form an electrostatic latent image. Thereafter, the irradiated member is re-charged with a scorotron charger while applying a voltage to the scorotron grid, the voltage being slightly lower than the surface potential of the image portion of the latent image, and being substantially higher than the background potential of the latent image and being of the same polarity as that of the charging. By this re-charging, the outline portion of the image is given lower potential than the other portion. Then, the outline portion of the image with the lower potential is developed by a reversal development by using a toner charged to a polarity the same as the polarity of charging of the latent image bearing member.

摘要： A copying apparatus in which a developing bias voltage to be applied to a developing sleeve by a power source is changed to adjust the density of a reproduced image, while the electric potential difference between the developing sleeve and a toner supply roller is kept constant. As a result, a density of toner on the developing sleeve is kept constant. Therefore, a development is effected under the condition in which the density of the toner is constant, so that the tone of the image of an original document is reproduced in a desired density.

摘要： An electrophotographic copying apparatus is capable of forming outline images. It comprises a first charging device, an exposing device, a second charging device and a developing device along a moving direction of a photoconductor. A sensor detects an amount of toner adhering to a reference image formed on the surface of the photoconductor. Supply of toner is controlled based on the detected amount.
