PURPOSE:To facilitate the inserting operation of an electric wire to each distribution wiring pulley by providing a center hole for electric wire insertion, an end surface groove cut radially from the opening edge of the center hole, and an outer peripheral hole communicating with the end surface groove to each distribution wiring pulley fitted to a one-side rotary support shaft end of each developing device. CONSTITUTION:Plural electric wires 86-89 connected to feed parts of respective developing devices 14a-14d are led out of opening ends of center holes 80a of respective distribution wiring pulleys 81-84 temporarily and then tip parts of the electric wires 86-89 are inserted into one desired groove part of cross- shaped end surface grooves 81a-84a and led out of one outer peripheral hole 80c opened in the groove end. Consequently, the inserting operation of the electric wires 86-89 to the distribution wiring pulleys 81-84 and the wiring operation of the respective electric wires 86-89 are facilitated. |
