Title:
CONDUCTIVE ROLL, IMAGE FORMING APPARATUS, AND INSPECTION METHOD FOR CONDUCTIVE ROLL
Document Type and Number:
WIPO Patent Application WO/2022/018933
Kind Code:
A1
Abstract:
This conductive roll comprises: a core having an outer peripheral surface along a circumference about the axis; and a surface layer arranged along the outer peripheral surface of the core. The surface layer includes a conductive portion having conductivity and a particulate surface roughness-imparting agent dispersed in the conductive portion. The surface roughness-imparting agent has an average particle size within a range of 6-10 μm inclusive-exclusive. The number of particles of the surface roughness-imparting agent included per unit area of the surface layer is within a range of 3.5×105 particles/mm2 to 7.5×105 particles/mm2 inclusive. The surface layer has an average thickness within a range of 0.2-5.5 μm inclusive.
