Abstract:
1. An electrostatic charge image developing toner comprising: a binder resin; a compatibilization-promoting material; and a release agent, wherein when a peak temperature during a first temperature increase and a peak temperature during a second temperature increase, that are obtained by differential scanning calorimetry including performing the first temperature increase at 10° C./min after holding at 10° C., performing cooling at −10° C./min, performing a heat treatment for 24 hours at 50° C., and performing the second temperature increase at 10° C./min, are represented by Tt1 and Tt2 wherein when a peak temperature during a second temperature increase, that is obtained by differential scanning calorimetry that performs a first temperature increase at 10° C./min after holding at 10° C., cooling at −10° C./min, and the second temperature increase at 10° C./min without performing a heat treatment, is represented by Tt2 wherein the compatibilization-promoting material is a liquid paraffin.
