A roller apparatus includes: a first roller provided in a curved medium transporting path and driven by a power source; and a second roller driven and rotating with a medium nipped between it and the first roller, wherein the second roller is located on a side in which, when the leading end of the medium enters between the rollers, the leading end of the medium comes into contact with the second roller due to the restoring force of the medium with a curved state as a result of the curved medium transporting path, and has on its outer circumferential surface a guide section for guiding the leading end of the medium between the rollers.
