PURPOSE:To convey a wide beltlike material without deviation with simple structure, by using a plurality of timing belts. CONSTITUTION:Conveyor 34 for carrying wide beltlike material 7, such as beltlike photoreceptor is composed by stretching narrow timing belts 28 and 28' around timing pulleys 18, 19, 20, 18', 19', and 20' mounted on drive shaft 25, idling shaft 26 and driven shaft 27. When material 7 is endless, it is conveyed in direct close contact to belts 28 and 28' and developed with developing roller 11, and when not endless, it is fixed with pins 41 on the outer surfaces of belts 28 and 28', so becomes conveyable and developable. Since belts 28 and 28' are narrow in width and cause no deviation, deviation of wide material 7 can be prevented. |
