A transport device for alternatively transporting a first sheet-like material which is a first size and a second sheet-like material which is second size different than the first size, to pass a charging portion which applies an electric charge of a predetermined polarity, includes a base member made from an insulating material, a first conductive guide member arranged on the base member along a transport direction of the sheet-like material, and a second conductive guide member arranged on the base member along the transport direction and apart from the first conductive guide. The first conductive guide member guides both the first sheet-like material and the second sheet-like material, and the second conductive guide member guides the second sheet-like material. Also, the transport device includes a voltage source coupled to the first conductive guide member and the second conductive guide member, a first switch arranged between the voltage source and the first conductive guide member, and a second switch arranged between the voltage source and the second conductive guide member. A polarity of voltage applied by the voltage source is approximately the same as the predetermined polarity. Furthermore, the transport device includes a control device for turning on the first switch when the first sheet-like material is guided, and for turning on the first switches and the second switch when the second sheet-like material is guided. |
