摘要：
[PROBLEMS] The present invention provides a modifier for an electrophotographic toner which is excellent in adhesiveness with various inks, coating materials, aluminum or other metals, or the like, a release agent of the electrophotographic toner, and a modified electrophotographic toner. [MEANS FOR SOLVING PROBLEMS] A release agent for an electrophotographic toner, which comprises an epoxidized low-molecular-weight ethylene polymer (B) which contains an epoxy group in the polymer chain of a low-molecular-weight ethylene polymer (A), and has (i) a density of 870 to 1,050 kg/m3, (ii) a melting point of 70 to 130° C., and (iii) a number-average molecular weight (Mn) of 400 to 5,000, and a modified low-molecular-weight ethylene compound (C) obtained from the epoxidized low-molecular-weight ethylene polymer (B) and a carboxylic acid compound; and an electrophotographic toner for developing an electrostatic charge image, which comprises the modified low-molecular-weight ethylene compound (C).
