  • Patent number: 10496029
    Abstract: The image forming apparatus includes an image carrier, a transferring member and a cleaning device. The cleaning device includes a cleaning member, a case and a toner seal. A refresh mode including a first operation and a second operation is executable when an image forming operation is not performed. The first operation is executed such that the image carrier is rotated in a counter direction and for a predetermined distance or longer. The counter direction is a direction opposite to the rotation direction of the image carrier at the image forming operation. The predetermined distance is a distance from a contact position where the cleaning member comes into contact with the surface of the image carrier to a transferring position where the transferring member transfers the toner image. The second operation is executed such that the transferred body is driven and the transferring member is applied with transferring bias.

  • Publication number: 20190184662
    Abstract: An object of the present invention is to form a tire component member having a desired shape by a ribbon winding method without depending on skill and experience of an operator. Test conditions including the number of windings of winding a ribbon rubber around a forming drum and a feed pitch for moving the ribbon rubber in an axial direction of the forming drum for each rotation of the forming drum are set (Step S11), and a test sample is prepared under the test conditions (Step S12). With respect to the prepared test sample, a width, a cross-sectional area, and a thickness distribution in a width direction are measured (Step S13). Based on these results, the test conditions are corrected to obtain a correction condition (Steps S14 to S19).
