Direct imaging method and equipment using recording electrode, magnetic brush, powdered toner, and insulating recording means

Printing equipment comprising:

• a recording electrode, a magnetic brush forming means having magnetic toner, a magnetic toner developer for producing a magnetic force, an insulating recording medium and a recording paper, wherein the recording electrode and the magnetic brush forming means are provided on opposite sides of the insulating recording medium, a toner image is formed on the surface of said recording medium by applying a voltage across said recording electrode and the magnetic brush forming means while the end of the magnetic brush contacts the surface of said recording medium through the powder toner of said magnetic brush forming means, and said toner image is transferred to the recording paper, and wherein the charges of magnetic toner remaining on said recording medium are discharged after transfer of the image, when said magnetic toner is adhered to said recording medium by being succeedingly attracted by means of the magnetic force from said magnetic toner developer and thereby collected in the magnetic toner developer.

A recording medium to be used in printing equipment having a recording electrode, comprising:

• (a) a base material layer made of insulating film and having a resistance in the range of 10.sup.12 to 10.sup.16 ohms/cm;
• and
• (b) an uneven layer formed on the surface of the base and having a thickness in the range of 5-15 .mu.m.
