<P>PROBLEM TO BE SOLVED: To provide an electrophotographic toner giving good image density, suppressing surface fogging and electric carrier spent, and having a wide non-offset range and excellent low temperature fixability. <P>SOLUTION: The electrophotographic toner contains at least a binder resin and a colorant. The binder resin contains a polyester resin obtained by using a diol component which contains 1,3-propanediol (A) being a non-petroleum monomer and isosorbide (B) being a non-petroleum monomer. In the polyester resin, the 1,3-propane diol (A) and the isosorbide (B) are included by 5 to 20 wt.% and 1 to 20 wt.%, respectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
