Document Type and Number:
Japanese Patent JP7429787
Kind Code:
B2
Abstract:
A conductive roller includes: a core member including an outer surface along and about an axial line thereof; and a surface layer arranged along the outer surface of the core member. The surface layer includes a conductive portion formed of a conductive resin composition, and a surface roughness imparting material in a form of particles dispersed in the conductive portion. An average particle size of the surface roughness imparting material is in a range of 6 micrometers or greater and 10 micrometers or less. The number of particles of the surface roughness imparting material per unit area of the surface layer is in a range of 1.0 × 104 particles per mm2 or greater and 2.0 × 106 particles per mm2 or less. An average thickness of the surface layer is in a range of 3.0 micrometers or greater and 15.0 micrometers or less.
