<p>PURPOSE:To conduct the transfer of a excellent quality image which is devoid of a fold or transfer unevenness or the like, by conducting electrification which is by means of a paper electrification means, selectively according to a transfer material. CONSTITUTION:A paper electrifier 60 is turnably supported with a shaft 60A as a support point, and its tip holds an electrification brush 61. In addition, it is possible that the brush 61 tip is put into a condition in which it is elastically press-welded and contacted against the peripheral surface of a transfer belt 71 by the rotary phase of an eccentric cam 62 which is in contact with a square hole 60B internally, or the electrifier 60 is turned clockwise and the brush 61 is put into a condition in which it is retreated from the peripheral surface of the belt 71. Whether the quality of a transfer material is the quality of an ordinary transfer paper sheet or the quality of an electric insulation material is inspected beforehand, and in the case of a transfer paper sheet, the cam 62 is turned by the output of a control portion, and the brush 61 is press-welded against the belt 71, and predetermined electrification voltage is impressed, and a distinct copy picture quality can be obtained. Meanwhile, in the case of being of transparency, the cam 62 is further turned, and forces the brush 61 to retreat from the belt 71, and the impression of electrification voltage is not conducted.</p> |
