Abstract:
A toner for a full color image-forming method comprising:a coloring agent; a binder resin comprising a first binder resin and a second binder resin, the first binder resin comprising a linear polyester resin consisting of polymerized divalent acid monomers and dihydric alcohol monomers and having a number-average molecular weight (Mn) of from 2,500 to 7,000, a weight-average molecular weight (Mw) of from 8,000 to 25,000, and a Mw/Mn ratio of 2 to 4, the second binder resin comprising a non-linear polyester resin having a number-average molecular weight (Mn) of from 3,500 to 11,000, a weight-average molecular weight (Mw) of from 40,000 to 250,000, and a Mw/Mn ratio of 10 to 35, and a ratio of the first binder resin to the second binder resin (the first binder resin:the second binder resin) being 15:85 to 85:15 by weight, a first releasing agent having a softening point of 55 to 110Â° C., and a second releasing agent having a softening point of 110 to 160Â° C.
