  • Publication number: 20200047488
    Abstract: A protective sheet is to be laid on an endless belt sheet and covers a surface of the endless belt sheet to protect the surface. When the protective sheet is laid on the endless belt sheet, the bending stiffness of the protective sheet is lower in the circumferential direction of the endless belt sheet than in the width direction that is orthogonal relative to the circumferential direction. Thus, the risk of being bent and damaged of the endless belt sheet is minimized and the cumbersomeness of the operation of replacing the endless belt sheet is remarkably reduced by using such a protective sheet.

  • Patent number: 10538081
    Abstract: A printing apparatus includes an image forming unit that forms an ink image, a transfer unit that transfers the ink image formed on a transfer member to a print medium in a transfer operation, and a liquid absorbing member that absorbs a liquid component from the ink image before the transfer operation. A recovery unit recovers absorption performance of the liquid absorbing member by applying a moisturizing liquid to the liquid absorbing member. A first estimation unit estimates, based on print data, an ink discharge amount of ink to form the ink image, and a second estimation unit estimates a liquid amount of the liquid component to be absorbed by the liquid absorbing member from the estimated ink discharge amount. In addition, a control unit controls an application amount of the moisturizing liquid by the recovery unit based on a result of estimation by the second estimation unit.
