Since the support 10b of the stencil paper 10 is in close contact with the point c, when the entire surface of the stencil paper 10 is charged with, for example, a negative charge by the paper charging corona discharge device 21, the support 10b has a volume resistivity of 10 9 Ω-cm.
For the following reason, the charge applied to the perforation h formed in the synthetic resin film 10a by the thermal head 14 flows to the plate cylinder peripheral wall 1c and is not charged.
However, since the non-perforated portion of the synthetic resin film 10a has a volume resistivity of 10 13 to 10 16 Ω-cm, it is negatively charged, and the potential difference at this time is approximately zero at the perforated portion and approximately 1000 V at the non-perforated portion. becomes. Next, the charged stencil paper 10 is sent to the developing device 22,
If the development is performed using negatively charged toner, the toner will not adhere to the non-perforated portions of the synthetic resin film 10a, but will adhere only to the perforated portions h of the support 10b. Further, the stencil paper 10 to which the toner is attached is sent to a toner charging corona discharge device 23, where corona ions having the same polarity as the toner are emitted, thereby performing more reliable toner charging. Next, the stencil paper 10 is sent to a transfer corona discharge device 25, and a printing paper 24 is superimposed on the synthetic resin film 10a side of the stencil paper 10, and a polarity opposite to that of the toner is applied from the side of the printing paper 24, that is, a positive polarity in this case. Corona ions are emitted. This allows the perforation h
The toner is electrostatically attracted to the printing paper 24.
その後被印刷紙２４はヒートローラ２６による
定着装置まで送られ、トナーは被印刷紙２４上に
定着されて印刷が施されるものである。 After that, the printing paper 24 is sent to a fixing device using a heat roller 26, and the toner is fixed on the printing paper 24 to perform printing.
この後、更に、新しい版を用いて印刷するとき
は前述の孔版原紙１０の製版動作を再び行えばよ
い。 After this, when further printing is to be performed using a new plate, the above-described stencil-making operation of the stencil paper 10 may be performed again.

構成としても良い。 Further, in the above embodiment, the thermal head 14 as a perforation plate-making means is provided inside the plate cylinder 1, but it is provided outside the plate cylinder at a position facing the delivery roller 16, so that it comes into contact with the delivery roller 16 and separates from it. It may be configured freely.
