发明名称 Power supply for a charging apparatus having a contact charger for charging an object to be charged
摘要 A charging apparatus includes a charging roller, contactable to an object to be charged, for charging the object to be charged, the charging roller being provided with a rotation shaft, an electroconductive bearing for supporting the rotation shaft, a contact member for urging the bearing to press-contact the charging roller to the object to be charged, wherein a first electric energy supply path is established from the contact member to the rotation shaft through the bearing to supply electric energy from the contact member to the rotation shaft, a power supply contacted to a peripheral surface of the rotation shaft, wherein the contact member urges the power supply to press-contact the power supply to the peripheral surface of the rotation shaft, wherein a second electric energy supply path is established to supply electric energy from the contact member to the rotation shaft through the power supply member, and the power supply member is movable in a direction of urging of the contact member independently of the bearing.
