Claims13
A toner for developing electrostatic latent images comprising:
- a binder resin comprising a first resin and a second resin;
- and a colorant;
- said first resin having a softening point of 95.degree. to 120.degree. C. and a glass transition point of 50.degree. to 75.degree. C., said second resin having a softening point of 130.degree. to 160.degree. C. and a glass transition point of 50.degree. to 75.degree. C., said first resin comprising a linear polyester resin obtained by a bivalent alcohol component and a bivalent carboxylic acid component, said second resin obtained by a raw monomer of the polyester resin, a raw monomer of the vinyl resin and a dual-reactive monomer, and said dual-reactive monomer being a raw monomer that is able to use dual reactions of a condensation polymerization and a radical polymerization.
