ABSTRACT:
A method of forming visible images in which magnetically attractable toner powder comprising resin particles containing magnetically attractable material is introduced to an image forming zone between an image registration medium and a moving conveying medium which has, within said image forming zone, a magnetic induction of at least 0.2T at its surface, thus imparting a force of attraction on the toner powder in which image forming zone the toner powder is selectively deposited on the image registration medium by electrostatic attraction in accordance with an image pattern, the toner powder used containing no more than 3% by volume of the magnetically attractable material.
