Backup roll with capacitive coating and an imaging device transfer station employing the backup roll
摘要
A toner transfer station of an electrophotographic imaging device employs a backup roll having an inner electrically grounded cylindrical metal base core and an outer surface layer disposed about the inner base core. The outer surface layer may be formed of a polyurethane elastomer material to provide a capacitive coating with a thickness greater than 15 microns, a dielectric constant less than 12 and a resistivity of less than 3.00E+13 Ohm-cm.
