    摘要: The paper feeding device of the present invention comprises a paper holder for holding a stack of large number of paper sheets; a first roller for sheetwise feeding out paper sheets from the stack in or on the holder; a regular rotation roller for further feeding each of paper sheets and rotatably mounted at a position downstream from the first roller when looking in the paper feeding direction; and a paging roller mounted in opposition to the regular rotation roller. The paging roller is driven always in such a rotational direction for drawback of sheet or sheets in the reverse direction relative to the regular and forward paper feed direction when one or more common class paper sheet or sheets or a plurality of special class paper sheet of a different quality then common class paper sheet is/are fed between the regular rotation roller and the paging roller. In addition the paging roller is rotated as a follower roller following the fed sheet under the action of the regular rotation roller when only one special class paper is introduced between the both rollers.

    摘要: In a process for reproducing images of fine lines of characters of low density, the latent image is initially transferred onto transfer paper such that charges, including the non-image portions of the original, are transferred onto substantially the entire area of the transfer paper so as to assure transfer of fine images and subsequently developing the transfer paper by a wet-type developing technique such that the transfer paper is passed through at least one electrode effective region having a greater potential than the potential of the non-image portion and a polarity the same as the potential of the areal image of the non-image portions, and also passing the transfer paper through at least one electrode non-effective region to clearly visualize only the latent image with the images of low densities.
