  • Publication number: 20200276820
    Abstract: An inkjet recording apparatus includes an ink jetter; a transfer unit that has an intermediate transfer body and transfers ink on its transfer surface to a recording medium to record an image; a thickening device that thickens the ink landed on the transfer surface before transfer to the recording medium; a cleaner that removes residual ink remaining on the transfer surface; and a hardware processor. The cleaner has a first ink remover that removes the thickened residual ink in first ink removing operation in which an adhesive member brought into contact with the thickened ink is separated from the transfer surface. If the transfer surface has a region occupied by the thickened ink of a predetermined reference area or more, the hardware processor causes the first ink remover to perform the first ink removing operation.

  • Patent number: 8837996
    Abstract: An image forming apparatus includes a transfer belt, a pressure receiving roller, a secondary transfer roller, and a belt movement restricting section. The belt movement restricting section is disposed close to the back of the belt. When pressing the belt between the pressure receiving roller and the secondary transfer roller, and nipping paper between the belt and the secondary transfer roller, an angle defined by the portion, upstream from the secondary transfer roller, of the belt and an imaginary line connecting the pressure-receiving-roller axis with the secondary-transfer-roller axis is less than 90 degrees. During non-secondary-transfer mode, the belt movement restricting section is separated from the belt. During secondary transfer, the belt movement restricting section holds the belt not to let the belt pushed by the paper move toward the pressure receiving roller.
