    摘要： An electrophotographic recording apparatus using an amorphous silicon hydride photosensitive drum for recording images through processes comprising uniformly charging the drum, exposing the drum to light to form a latent image thereon, developing the latent image and transferring the developed image onto a recording medium wherein the charging and transferring processes are implemented by corona dischargers. To prevent pale or blurred image recording which occurs when the image recording is resumed after expiration of a long period of time, a shielding means is provided in association with each of the corona dischargers for shielding the corona discharger to interrupt atmospheric contact with the peripheral surface of the photosensitive drum.

    摘要： A developing unit includes a plurality of developing rolls over which a developer is conveyed and supplied onto an image carrier which is rotatably supported; and at least one pair of the developing rolls being adjacent to each other. In the pair of the developing rolls, one developing roll rotates in a direction opposite to a rotary direction of the image carrier, and the other developing roll rotates in the same direction of the rotary direction of the image carrier. A regulation member is interposed between the pair of the developing rolls. The regulation member regulates a conveyed amount of the developer. The regulation member is disposed to be opposed to a magnet which is provided within the two adjacent developing rolls. A polarity of the magnet in the pair of developing rolls opposed to each other is different from each other.

    摘要： An image forming apparatus has an image retaining body which is supported so as to be able to move endlessly, a transfer means which is installed at a specific distance away from the surface of the image retaining body or in contact with the surface of the image retaining body, and a paper guide which is installed upstream and downstream, of or at least upstream or downstream the transfer means along the moving direction of the image retaining body for guiding a sheet of paper between the image retaining body and the transfer means and for pressing the paper onto the surface of the image retaining body. The image forming apparatus is equipped with an adjusting means for adjusting the distance between the paper guide means and the transfer means along the moving direction of the image retaining body, thereby varying the length of the paper wound onto the image retaining body.

    摘要： A transport roll 1 consists of a metal roll 3 of 40 mm in diameter covered with a conductive PFA tube 2 of 10.sup.10 .OMEGA.cm in volume resistivity and 200 .mu.m in thickness. A DC voltage source 4 is connected to the metal roll. A sheet of paper 5 bearing toner images 6 and 7 on both sides thereof receives a drive force from a paper drive roll, and turns with the movement of the paper. The DC voltage source produces voltage VB1 of the same polarity as the charging polarity (positive) of the toner image 6 being in contact with the transport roll. The voltage VB1 is optimumly controlled so as to prevent the transport roll from being soiled with toner.
