Document Type and Number:
WIPO Patent Application WO/2016/098616
Kind Code:
A1
Abstract:
A toner for electrophotography containing an ester wax and a binder resin containing a crystalline composite resin C and an amorphous polyester A, wherein: the crystalline composite resin C is a resin including a styrene-based resin component and a polycondensation resin component obtained by performing polycondensation on an alcohol component containing a C9-14 aliphatic diol and a carboxylic acid compound containing a C9-14 aliphatic dicarboxylic acid compound; and the mass ratio between the amorphous polyester A and the crystalline composite resin C (amorphous polyester A/crystalline composite resin C) is 60/40 to 95/5, and the mass ratio between the crystalline composite resin C and the ester wax (crystalline composite resin C/ester wax) is 0.5 to 9. The toner for electrophotography can be suitably used, e.g., for development of a latent image formed in electrostatic image development, electrostatic recording, electrostatic printing, or the like.
