Abstract

PURPOSE:To obtain a toner of good durability in which the quantity of electric charge is stable and by which good images are obtained at high temp. and high humidity by containing an inorg. oxide of tin oxide system in a binder resin for the toner. CONSTITUTION:The toner contg. a tin oxide type inorg. oxide such as SnO2, SnO2- TiO2 or the like at 0.1-10wt% basing on the weight of a binder resin such as a (co)polymer of a styrene-butadiene resin or the like or a condensation polymer such as epoxy resin or the like, and added with necessary pigments or dyes, carbon black, etc., and in the case of a magnetic toner, magnetic powder, is produced. By the adding of said oxide, the images of good uniformity which are free from photographic fogs, are highly durable, and have no density irregulaties from low to high humiditides are obtained with both of the toner for two component type developers using carriers and one component magnetic toners.
