Abstract
Image forming particles for use in electrostatic image formation, which particles have a light transmitting property, said particles comprising an electrically conductive material and subliming substance. The electrically conductive particles exhibit superior translucency which enables a charge preliminarily imparted to a photoconductive support member to be readily erased upon exposure to light image from an original, with consequent reduction of electrostatic attraction between the particles and the support member to minimum for presenting clear and definite images without fogging. Furthermore, the particles are electrically independent due to absence of electrostatic attraction therebetween and because of their electrical conductivity adhere to the support member by electrostatic induction of the charge imparted to the latter without adhesion between the particles, thus being uniformly arranged on the support member in one single layer and as close to each other as possible, thus offering resultant images of superior quality.
