  • Publication number: 20240301236
    Abstract: An electrophotographic roller comprising a substrate comprising a conductive outer surface and a resin layer on the outer surface of the substrate, wherein the resin layer comprises a polyurethane having a polycarbonate structure, an impedance at a frequency of 1.0×100 to 1.0×101 Hz is 1.00×106? or more when a specific AC voltage is applied to the outer surface of the electrophotographic roller while a frequency is changed between specific range, and when a corona discharger having a grid part is moved along an axial direction of the electrophotographic roller at a speed of 400 mm/sec, a maximum value of an electric potential of the outer surface is less than 20.0 V when measured at 0.06 seconds after a passage of the grid part.
