The purpose of the present invention is to provide a blade for an electrophotographic device, said blade having a supporting member and an elastic rubber member firmly attached via an adhesive layer. This blade for an electrophotographic device has the elastic rubber member attached to the supporting member via the adhesive layer. The adhesive layer comprises a cured urethane-based moisture-curable hot-melt adhesive and is characterized by having a surface membrane formed at least at the site where the supporting member comes in contact with the adhesive layer, said surface membrane containing a silicon compound and having a silicon content of at least 6 wt% when quantitatively analyzed using fluorescent X-ray analysis.
