Abstract
An intermediate transfer member for electrophotography comprising a substrate and a surface layer provided on the substrate. The surface layer comprises a binder resin and a perfluoropolyether. An extraction amount of the perfluoropolyether per 10 mmof the surface layer, is 0.10 mg to 5.00 mg, the extraction amount of the perfluoropolyether obtained by immersing the intermediate transfer member into a solvent that can dissolve the perfluoropolyether at 25° C. for 24 hours. A surface of the intermediate transfer member that is not subjected to first and second treatments, has a n-hexadecane contact angle of 55° or more. A surface of the intermediate transfer member that has been subjected to the first treatment, has a n-hexadecane contact angle of 40° or less. A surface of the intermediate transfer member that has been subjected to the second treatment, has a n-hexadecane contact angle of 50° or more.
