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

    摘要： Provided is a developing roller for stably outputting even images having high quality and excellent durability even after the roller is left over long in a severe high-temperature high-humidity environment. Also provided are a process cartridge and an electrophotographic device each including the developing roller. The developing roller comprises a core shaft, an elastic layer, and a surface layer with which the surface of the elastic layer is covered, and is characterized in that the surface layer contains a urethane resin, the urethane resin having, between adjacent two urethane bonds, the following structure A) and/or structure B): A) the structure represented by structural formula (1) and at least one structure selected from the group consisting of the structure represented by structural formula (2) and the structure represented by structural formula (3); and B) the structure represented by structural formula (4). The roller is further characterized in that the surface layer contains polyurethane resin particles having an indentation recovery, as measured in accordance with ISO 14577-1, of 80% or higher.
