Abstract: A tape processing device has a feed device, a cutter assembly, and a coating device. The feed device feeds a tape having a layer of an adhesive. The cutter assembly has at least one cutting blade and cuts the tape. The coating device applies an adhesion-preventing liquid on the at least one cutting blade of the cutter assembly to thereby prevent any of the tape and the adhesive of the tape from adhering to the at least one cutting blade of the cutter assembly.

Abstract: A method of electrically charging a material to be charged by bringing a charging member impressed with a voltage into physical contact with the material to be charged, wherein the charging member is constituted by a flexible and electrically conducting endless sheet and a rotary insulating brush which supports the endless sheet at a position where the endless sheet and the material to be charged are in contact with each other and gives a pushing force to the endless sheet, and the endless sheet is driven actively or passively together with the insulating brush at a speed substantially in synchronism with the material to be charged while applying a charging voltage to the endless sheet. This method makes it possible to uniformly and stably charge the surface of the photosensitive material even when defects such as pinholes or the like exist in the surface of the photosensitive material, without causing the life of the photosensitive material to be shortened.
