发明名称 Toner for electrostatic image development
摘要 The toner for developing the electrostatic latent image of the present invention is composed of a toner particles containing at least a binder resin, a colorant, a charge control agent and a parting agent, the toner particles having a volume mode diameter (a) in the range from 5 to 10 mum, the ratio (Dv/Dp), of a volume average particle diameter (Dv) to a number average particle diameter (Dp), from 1.0 to 1.3, and an average circle degree in the range from 0.94 to 0.97, the toner particles having a standard deviation (b) not more than 2.5 mum of particle diameter, a ratio (C1/C2) from 1.01 to 1.03, wherein c1 represents an average circle degree of the toner particles having a particle diameter not less than (a-2b) mum to less than a mum, and c2 represents an average circle degree of the toner particles having a particle diameter not less than a mum and less than (a+2b) mum, and the toner for developing an electrostatic latent image having a content, of an isopropyl alcohol extract component, of 5% by weight or less. The toner for developing an electrostatic latent image of the present invention is excellent in shelf stability, difficult to cause fog and excellent in cleaning properties and charging stability.
