PURPOSE:To increase the efficiency of the exchange work of a transfer belt and to prevent the degradation of the performance of the transfer belt by providing a movable means pulling out a transfer device including the transfer belt from a main body device inside the transfer belt. CONSTITUTION:The rail for pulling out (movable means) 23 and a supporting member 22 are provided inside the transfer belt 12. When the transfer belt 12 is exchanged, the transfer device 30 is pulled out from device main body 31 along the rail for pulling out 23. Then, the positioning member of the tension roller 14 of the transfer belt 12 is loosened to move the position of the tension roller 14 and pull out the transfer belt 12 in a direction perpendicular to a rotational direction. A novel transfer belt 12 is inserted in the direction opposite to a pulling out direction to turn the positioning member and move the tension roller 14 to a fixed position. In this state, the transfer device 30 is inserted along the rail for pulling out 23 to complete the exchange of the transfer belt. In other words, the rail for pulling out 23 is provided inside so that the exchange and maintenance of the transfer belt are easily executed. |
