摘要：
An electrostatic photographic method for reversal development using a magnetic brush, with the magnetic brush and photoconductive drum being grounded, and with the development being performed using a dry reversal developer comprising 100 parts by weight of a carrier having ferromagnetic properties and 1 to 10 parts by weight of a toner having a volume specific resistance falling within the range between 3.5.times.10.sup.9 and 1.times.10.sup.11 .OMEGA.-cm.
