Abstract: A nonmagnetic single-component developer is manufactured by admixing fluoropolymer fine powder to a toner containing a thermoplastic binder resin and a coloring pigment in an amount of 0.1 to 10% by weight of the resultant mixture. The fluoropolymer fine powder has a weight-average particle size smaller than that of the toner, and the amount of particles each having a size not larger than 3 .mu.m and contained in the fluoropolymer fine powder is not larger than 30% by weight. The method may be such that classifying by particle size is effected to the mixture of the toner and the fluoropolymer fine powder to remove smaller particles present therein.

Abstract: Disclosed is an electrostatic image developer with negative chargeability which can give clear image quality and high image density by virtue of the toner, contained therein, having a small-diameter or a high content of fine toner particle, surface-modified with a fluoropolymer fine particle.
