摘要： An image forming apparatus has a plurality of developing containers for developing an electrostatic latent image of a latent image carrier by toners having colors different from each other except for black; a black developing container for color for storing black toner for color and operated when the developed image on the latent image carrier every color is overlapped and transferred onto a transfer material to provide a color image; a black developing container for a monochromatic image for storing black toner for a monochromatic image and operated when the monochromatic image is obtained; and a device for arranging the respective developing containers such that the developing containers are opposite to the latent image carrier. The other image forming apparatuses are also shown.

摘要： An image forming apparatus of the type forming a toner image on a photoconductive drum or similar image carrier, transferring it to a paper or similar transfer medium via an intermediate transfer body, e.g., belt, and fixing it on the medium by a fixing device is disclosed. Just after the transfer of a toner image of the last color which is to lie over the other toner images on the intermediate transfer belt, the peripheral speed of the belt is switched to a comparatively low speed matching a fixing and paper transport speed. At this instant, the belt is moved away from the drum. The length of the transfer medium and the distance between a paper transfer position and a fixing position is compared. For a relatively short transfer medium, the peripheral speed of the belt is not switched to the low speed.

摘要： A copier, laser printer or similar image forming apparatus of the type having an intermediate image transfer body in the form of a belt allows documents to be reproduced in a page-sequential paper discharge mode which discharges paper sheets, or recording media, in order of page. When an automatic two-sided copy mode is selected, the apparatus automatically sets up the page-sequential paper discharge mode. Hence, when two sided black-and-white documents and color documents are reproduced together in the automatic two-sided copy mode, paper sheets are driven out of the apparatus in order of page.

摘要： An image forming apparatus for forming an image on one or both sides of a recording medium includes a rotatable photoconductive element on which latent images are optically written, a developer which develops the images to produce a primary toner image on the photoconductive element, a belt which faces the photoconductive element, and onto which the toner image is transferred when a paper sheet is not present. A charged roller is close to and above an upper portion of the belt and downstream from the photoconductive element. The charged roller holds the paper on the belt and also transfers toner onto the underside of the paper.

摘要： An image recorder capable of preventing a non-fixed toner image carried on a paper sheet from being rubbed with no regard to the elasticity or the thickness of the paper sheet. A belt transports the paper sheet with a non-fixed toner image. An upper guide plate and a lower guide plate face each other for guiding the paper sheet to a fixing device. The relative position of the upper and lower guide plates and the belt is variable to prevent the non-fixed toner image from contacting the upper or lower guide plate.

摘要： The current methods and systems for cleaning residual ultra-fine spherical toner from an image forming surface discloses the application of aspherical toner to a cleaning blade. The aspherical toner is generally larger than the ultra-fine spherical toner which provides a superior image on an image-carrying medium. According to one preferred embodiment of the current invention, the aspherical black toner is placed in a predetermined area outside of a desired image area where the ultra-fine spherical toner in multiple colors is placed. The aspherical toner is transported to the cleaning blade before the multi-color toner reaches the cleaning blade. Since the aspherical toner applied at a contacting edge of the cleaning blade provide an effective seal or trap between the cleaning blade and the image forming surface, the ultra-fine spherical toner is effectively removed from the image forming surface.

摘要： An image forming apparatus which insures stable image transfer at all times with no regard to aging and environment. An electrometer is located in close proximity to and opposite to a transfer region where an image carrier and a transfer medium face each other. A voltage to be applied to an electrode which applies a transfe voltage to the transfer medium is controlled in response to the output of the electrometer such that the electric field in the transfer region remains constant.
