Original Abstract Submitted
an electrophotographic member comprising: at least a base layer; an elastic layer; and a surface layer in this order, wherein the surface layer comprises a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, at an endothermic curve upon performing two measurements at a ramp up rate and a ramp down rate both set at 20� c./min using a differential scanning calorimeter (dsc) with a sample sampled from the surface layer as a measurement sample, an endothermic peak temperature in a second temperature raising process is 304� c. or less, an endothermic quantity in a first temperature raising process is 21j/g or more, and d3 is 40 �m or less, where d3 represents an area average diameter of a spherulite at an outer surface of the surface layer.
