ABSTRACT:
A toner for electrophotography, containing a resin binder containing a polyester-based resin (A) and a polyester-based resin (B) having a softening point of a temperature higher than the polyester-based resin (A) by 10° C. or more, wherein at least one of the polyester-based resins (A) and (B) is a resin derived from a (meth)acrylic acid-modified rosin, having a polyester unit obtainable by polycondensing an alcohol component and a carboxylic acid component containing a (meth)acrylic acid-modified rosin, and a method for producing the toner. The toner for electrophotography of the present invention is usable in, for example, developing or the like latent images formed in electrophotography, electrostatic recording method, electrostatic printing method or the like.
