Abstract
Disclosed is a negative-electrification toner for use in electrophotography. The toner comprises a resin, essentially consisting of a solid silicon varnish, and a colorant so that the resultant latent image can be easily erased or eliminated by the use of a rubber eraser. The novel toner, essentially consisting of a solid silicon varnish, has a low softening point and, as a result, the latent image produced can be easily erased.
