Tona~
σ] Form a mirror-symmetrical image and use it as an electrostatic printing master plate,
It is carried out using an electrostatic printing method with a print size of about 10 to 108, and printed matter can be obtained in a short time and at low cost. In particular, an electrostatic printing device is characterized in that it does not require an exposure section and a cleaning section. The reason why a cleaning section is not required is because the reversal development method is used, which uses toner with the same polarity as the charge charged on the electrostatic printing master plate.As a result, the life of the electrostatic printing master plate is extended. It also prevents toner loss. Furthermore, since there is no b-exposed area, it greatly helps to increase printing speed.
