Further, upon occurrence of the insulation being deteriorated, the high voltage control unit can stop the high voltage supply. | 05-12-2011 |

A cover member is fitted on the housing member to cover an outer surface of the housing member. Opposite axial ends of the cover member are fitted on and attached to opposite axial ends of the housing member so as to leave an annular gap space between the cover member and the housing member. The annular gap space keeps almost entire radially confront areas of the cover member and the housing member, preventing high voltage electrostatic charges on the outer surfaces of the cover member from leaking through the housing member. | 02-05-2009 |
