    摘要： The color image forming method of the kind sequentially forming toner images of different colors on an image carrier with developers of corresponding colors stored in a plurality of developing devices, sequentially transferring the toner images to a single paper or similar recording medium one above the other, and returning the toner left on the image carrier after the image transfer to the developing devices color by color, and an image forming apparatus practicable therewith. After the transfer of a toner image of any particular color to the paper wrapped around a transfer drum, a cleaning roller assigned to the above color each collects the toner remaining on the drum and again deposits it on the drum. The drum conveys the redeposited toner to one of the developing devices storing a developer of the same color as the toner.

    摘要： A sheet feeder incorporated in an image forming apparatus and allowing the distance between the preceding sheet and the succeeding sheet to be reduced to a minimum necessary one. A pair of control rollers whose transport speed is controllable are located upstream of an image forming section with respect to an intended direction of sheet transport. An image transfer and paper separation unit is located at the image forming section. The transport speed of the control rollers is made higher than an image forming speed for any desired period of time after the leading edge of a sheet has been gripped by said control rollers and before the leading edge reaches the image forming section. As a result the distance between the preceding and succeeding sheets is reduced to increase the number of images which can be formed for a unit time without the transport speed at the image forming section being increased.

    摘要： An image forming apparatus is provided with sensors for detecting existence of sheets of paper at a plurality of positions in transport paths within the image forming apparatus. A circuit part counts a number of sheets of paper remaining within the image forming apparatus when a transport abnormality occurs based on outputs of the sensors. This number of sheets of paper remaining within the image forming apparatus when the transport abnormality occurs is displayed on a display.

    摘要： An image forming system includes an image forming apparatus, a physical property detector, a data storage device, and a latent image carrier replacement time detector. The image forming apparatus includes a replaceable latent image carrier, forms a latent image on a surface of the latent image carrier, develops the latent image into a visible image, and transfers the visible image onto a recording medium. The physical property detector detects predetermined physical properties of the image forming apparatus in a continuous manner or an intermittent manner. The data storage device stores, as a specific physical property, data on at least one of the detected physical properties, which changes before and after replacement of the latent image carrier. The latent image carrier replacement time detector detects, on the basis of changes over time of the stored specific physical property, a latent image carrier replacement time.
