  • Publication number: 20200019093
    Abstract: An intermediary transfer belt having surface resistivity ?s of 1×109 ?/square or more and volume resistivity ?v of 1×1012 ?·cm or less includes a thermoplastic resin material containing carbon black. The carbon black contained in the thermoplastic resin material has a weight ratio of 22.5-28.5 weight % and include first carbon black and second carbon black. The first carbon black of the carbon black contained in the thermoplastic resin material has a weight ratio of 50-90 weight % and dibutyl phthalate absorption of 93-127 ml/100 g, and the second carbon black of the carbon black contained in the thermoplastic resin material has a weight ratio of 10-50 weight % and dibutyl phthalate absorption of 36-79 ml/100 g.

  • Patent number: 8116641
    Abstract: The image forming device, by providing an amount of toner remaining detection system, calculates the amount of relative change in the electrostatic capacitance in the amount of toner remaining over a prescribed number of sheets of recording paper (R) to sense the amount of toner remaining, and indicates that the amount of toner remaining is too low when it is judged that the amount of relative change in the electrostatic capacitance of said amount of toner remaining exceeds a reference amount of change, sensing of the amount of toner remaining and indication that it is too low are performed based on the relative change in one sensing signal relating to the amount of toner remaining, comparing two sensing signals relating to the amount of toner remaining as in the past is eliminated, and the process for adjusting the sensing output is made unnecessary.

  • Publication number: 20070196115
    Abstract: In the image forming device, a discrepancy in timing of a control sequence is corrected, which is caused by abrasion of a paper sheet detection member placed on a paper sheet transport path from a paper feeder to a transfer part, the paper sheet detection member contacting the paper sheet to detect a paper sheet. A registration sensor functioning as the paper sheet detection member is placed on the paper sheet transport path from the paper feeder to the transfer part, and it contacts the paper sheet to detect a paper sheet. In transporting the paper sheet, time T? from when the paper sheet detection member detects the trailing edge of the paper sheet until when the trailing edge of the paper sheet passes through the transfer nip part is measured, and a difference ?T between the time T? being measured and a predetermined reference time T is obtained.
