PURPOSE:To contrive the improvements of hot offset resistance and lower temp. fixing property by consisting this agent of an ethylene-propylene series resin with a specific melt viscosity, and constituting a random structure with ethylene and propylene. CONSTITUTION:The agent is consisting of the ethylene-propylene resin with 60-1,000cps melt viscosity at 160 deg.C and the ethylene-propylene has a random structure. As a composition of the ethylene-propylene resin the ethylene content is preferable normally <=25wt.%, particularly preferred from <=10wt.% to >=1wt.% and the propylene content is normally from >=65wt.% to <=99wt.%, preferred from >=90wt.% to <=99wt.%. Hence a sufficient hot setoff temp. is obtained and the excellent releasing agent for electrophotographic toner at the lower temp. fixing property is obtained. |
