ELECTROSTATIC IMAGE DEVELOPING TONER AND METHOD FOR PRODUCING THE SAME |
摘要 |
An electrostatic image developing toner includes: a binder resin containing a crystalline polyester resin and an amorphous resin, wherein when, in differential scanning calorimetry of the toner according to ASTM D3418-8, a temperature of an endothermic peak derived from the crystalline polyester resin in a first heating process is defined as Tm1 (° C.), an endothermic quantity based on the endothermic peak in the first heating process is defined as ΔH1 (J/g), an endothermic quantity based on the endothermic peak in a second heating process is defined as ΔH2 (J/g), and a softening temperature is defined as Tf1/2 (° C.), Tm1 is 60 to 80° C., Tf1/2 is 95 to 125° C., and ΔH1 and ΔH2 satisfy the relationship represented by the following Formulae (1) and (2):;[Math. 1];0.65≦ΔH2/ΔH1≦0.95 (1);205−(1.4×Tm1)<Tf1/2≦220−(1.4×Tm1) (2) |
