摘要：A high-quality developing member which excels in filming resistance and excelsin leak resistance despite high electroconductivity is provided. The developing memberincludes an electroconductive substrate, an elastic layer formed on the substrate, and asurface layer which covers a surface of the elastic layer. The surface layer includes a firstresin which has, between two adjacent urethane linkages, a structure represented by thestructural formula (1) and one or both of structures selected from the group consistingof a structure represented by the structural formula (2) and a structure represented bythe structural formula (3), a second resin which has a structure represented by thestructural formula (4) and one or both of structures selected from the group consistingof a structure represented by the structural formula (5) and a structure represented bythe structural formula (6), and an electronically conductive filler.
