PURPOSE:To obtain a copying machine shortened in the charging device, by bending a wire in the tension direction at the contact point, fixing it, and omitting the useless length of the end of the housing. CONSTITUTION:The figure A shows a section obtained by cutting the charging device D seated at the prescribed position of an image bearing drum S with a plane rectangular to the wire axis aD of the device D and the rotational axis aS of the drum S, and the figure B shows an optional plane pD obtained by freely turning a plane contg. the axis aD. On the plane pD, the wire stretched along the axis aD is bent at the contact point P by an optional angle alpha, preferably 60-180 deg., and it may be bent by plural times on an optional plane intersecting the plane pD. In the upper figure, the wire 3 is bent by alpha=90 deg. at the contact member 8 and fixed, and C is the frame of the machine, and 9 is the seat member of the charging device D1 installed on the frame C. |
