    摘要： The apparatus comprises a projection optical system and a copying system. The projection optical system can project an image of an original either onto a screen or to an exposing position of the copying system by switching between two positions. The copying system comprises a plurality of chargers providing different charging conditions in accordance with the types and sizes of copy sheets, by utilizing a change-over switch. A plurality of switches adapted for use with copy sheets of different lengths are arranged along the path of movement of a sheet of paper and, when the switch corresponding to the particular length of copy sheet desired is actuated, the movement of the sheet of paper is stopped, so that the central portion of the copy sheet can be brought into alignment with the optical axis for exposing at all times regardless of the difference in the length of copy sheets. Apparatus can interchangeably mount either a pressing plate assembly for manually feeding one original after another or an automatic feed device which can automatically feed one by one a plurality of originals to the exposing position of the copying system and to eject the same therefrom. By switching between the charging conditions of the chargers, it is possible to produce a positive duplicate of an original irrespective of whether the original is negative or positive. The pressing plate assembly and automatic feed device comprise carriers for effecting moving in X-and Y-directions which are interchangeable, so that it is possible to select a carrier which best suits the size of an original and the amount of movement of the original. The projection optical system comprises a blind coupled to a reflector so as to prevent light from the screen from reaching the exposing position of the copying system, the reflecting surface automatically facing downwardly when the power source is turned off.

    摘要： In the roller charging apparatus according to the present invention, the charging roller includes a layer of an epichlorohydrin rubber, so that it is possible to eliminate electric nonuniformity of a conductive elastic layer and to be charged by loading only a DC voltage. The charging roller also may have a surface layer formed of polyamide resin or fluorine resin. In addition durability can be improved by setting the roller hardness of the charging roller to 42 (measured by a JISA hardness meter) or more. Further, a roller diameter D.sub.r of the charging roller and drum diameter D.sub.d of the photosensitive drum may satisfy the relation of D.sub.d /D.sub.r .gtoreq.4. A cleaner can also be provided for removing foreign materials, such as toner, from the charging roller, and the cleaner may have a rubber hardness less than that of the charging roller.

    摘要： A continuous plural page copying method for a copier determines the size and lengthwise direction of a document which is laid on a glass platen, and produces magnifications on the basis of a relationship between one half of the size of the document in the lengthwise direction and the size of the papers selected. Consecutive pages of the document are reproduced continuously with no regard to the orientation of the document on the glass platen relative to the scanning direction of a scanner. The method reproduces an image on a paper while desirably matching it to the size of the paper.

    摘要： An electrophotographic image forming apparatus using a charge roller for uniformly charging the surface of a photoconductive element, or image carrier, during image formation, and a charging device having the charge roller. The charging efficiency is enhanced, and a uniform charge distribution is set up by the application of a DC voltage only. This suppresses the increase in the cost of an apparatus, the increase in power source cost, and the generation of a great amount of ozone. As a result, a charging member and a photoconductive element are prevented from being deteriorated while environmental pollution is eliminated.
