Abstract
A magnetic imaging system wherein a magnetizable recording member comprising a substrate overcoated with a magnetic recording layer of magnetic particles dispersed in a binder is exposed to high energy light pulses of sufficient energy effective to cause or allow the removal of said magnetic recording layer in exposed regions thereof. Imagewise configured high energy light pulses result in the removal of imagewise configured portions of the magnetic recording layer. Removal of portions of the magnetic recording layer can occur either before or after magnetization of the magnetizable recording member and upon development with magnetic toner, a complementary magnetic toner image is formed and can be transferred to a receiving medium to form hard copy. The system is particularly applicable to the formation of a magnetic master which is used to form the same magnetic toner image numerous times.
