Document Type and Number:
WIPO Patent Application WO/2019/050013
Kind Code:
A1
Abstract:
Provided is a developer carrier which is capable of stably forming high-quality images even in cases where a recording paper containing much talc is used. This developer carrier comprises a conductive substrate and a surface layer that is arranged on the substrate and contains a resin. The surface layer has a thickness of from 1.0 μm to 100.0 μm (inclusive); the Martens hardness at an indentation depth of 0.1 μm as determined by pressing a Vickers indenter into the surface layer from the outer surface in the thickness direction is from 50.0 N/mm2 to 100.0 N/mm2 (inclusive); the Asker C hardness as determined from the outer surface of the surface layer is from 75° to 90° (inclusive); and the value of the work function of the outer surface of the surface layer is from 5.6 eV to 6.0 eV (inclusive).
