PURPOSE:To simplify the work for attaching a transfer roller facing the surface of a photoreceptor drum and a high voltage board for applying a high voltage to the transfer roller, etc., in an electrostatic image forming device. CONSTITUTION:A transfer unit base 8 is formed into a shape like an open case by the rear surface of a base plate 8a, a supporting part 31 for supporting the transfer roller 9 and a passage guiding member 32 for making the passage of a paper sheet P smooth are provided on the surface side of the base plate 8a and engaging pawls 39 are provided on the inside surfaces of base part side plates 8b and attaining support so as to cover almost all the wide range surface of the high voltage board 26 in a case part. Moreover, a coil terminal 36 in elastically pressurized contact with a plate like electrode part 38 formed on the wide range surface of the high voltage board 26 is made to face the rear surface side of the base plate 8a and the terminal 36 is connected to a wiring 37 connected to the transfer roller 9. |
