とを備えた絶縁性フイルムベルト転写装置。 An insulating film belt that guides the transfer paper to the photoconductor. A transfer corona charger performs corona charging from the back side of the insulating film belt to transfer the toner image on the photoconductor to the transfer paper, and also separates the transfer paper from the photoconductor. a second corona that preliminarily directly charges the insulating film belt before it comes into contact with the transfer paper, and shares the charging of the insulating film belt with the transfer corona charger; The transfer efficiency is stabilized by controlling the voltage applied to the charger and at least one of the second corona charger and the transfer corona charger according to the paper quality such as the thickness, resistance, and capacitance of the transfer paper. An insulating film belt transfer device comprising:
