摘要:
An electrophotographic toner contains a resin, a colorant and a releasing agent. The releasing agent has a solidifying point of from 79° C. to 109° C., and one peak in an endothermic curve measured by a differential scanning calorimeter. A difference between temperature to give a maximum endothermic peak of the releasing agent and an end-set temperature of the releasing agent is within 10° C. A melt viscosity of the releasing agent at 110° C. is in a range of from 4 mPa.s to 9 mPa.s. The releasing agent in one particle of the toner forms 3 or more domains. Domains having a ratio of a major axis to a minor axis which is in a range of from 5 to 15 occupy 90% or more by number based on the total number of domains.
