Claim 2:
3. The electrophotographic toner composition according to claim 1, wherein the polymer (A) has a melting peak temperature Tm of 313 to 373 K as measured by DSC, and the polymer (A) satisfies the following relational expression (2):

1.6≤ln(G′Tm−10)/ln(G′Tm+30)≤2.6  relational expression (2):

wherein G′Tm−10 is the storage modulus in Pascals of the polymer (A) when the polymer (A) has a temperature of (Tm−10) K; and G′Tm+30 is the storage modulus in Pascals of the polymer (A) when the polymer (A) has a temperature of (Tm+30) K.
