ABSTRACT:
An electrostatic printing method, wherein a photosensitive member has a photoconductive layer formed on a support member with a conductive layer therebetween is placed face to face with a drum of electrostatic information recording medium, which has an insulating layer formed on a cylindrical conductive layer. Voltage is applied between the photosensitive member and the conductive layer of the electrostatic information recording medium drum. Electric charge is accumulated in the shape of an image on the surface of the electrostatic information recording medium drum, by performing image exposure from the direction of the photosensitive member. Recording film is supplied at the same speed as the rotating speed of the drum on contact or non-contact basis with the drum, and toner development is performed by a developing machine which is installed face to face to the drum with the recording film therebetween. A conductive roller may be provided at a position where the recording medium is separated from the drum.
