摘要： The disclosure relates to a method, using an electrophotographic system, including a first process of transferring the image of an original document to a copy sheet and a second process of transferring a half-tone solid on a specified region of the image on the copy sheet transferred at the first process. Accordingly, for example, when a copy sheet is white, a black toner is used in the first image forming process, and a white toner is used in the second image forming process, a white half-tone solid of the white toner is superimposed on the black toner image. As a result, the black toner image formed on the specified region looks soft half-tone.

摘要： An electrophotographic copying process produces a photocopy having a negative image in order to highlight information in a specified area. An original image is radiated onto a photosensitive medium to form a first image. A solid block is formed in the specified area of the first image. The first image is then transferred to blank paper. The original image is then radiated onto the photosensitive medium again and a portion of the image is erased in order to form a second image. The second image is then transferred to the sheet of paper having the first image. The resulting image formed on the sheet of paper includes a highlighted second image formed in the specified area.

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. In an outline image forming mode, an amount of toner to be supplied is set to a value smaller than an amount in a standard image forming mode.

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

摘要： The present invention relates to 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 a negative image to form an electrostatic latent image. Thereafter, the irradiated member is re-charged with a scorotron charger while applying a voltage to a grid, said voltage being lower than the surface potential of the non-image portion of the latent image, being higher than the potential of the image portion of the latent image and being of the same porality as that of the charging. By this re-charging, in one embodiment, the outline portion of the image has lower potential than the other portion. Then, the outline portion of the image with lower potential is visualized with a reversal development by using a toner charged to a polarity same as the polarity of charging.Or in another embodiment, the outline portion of the image has higher potential than the other portion. Then, the outline portion of the image with high potential is visualized with a normal development by using a toner charged to a polarity opposite to the polarity of charging.
