In a printer body 2 of a printer apparatus 1, a grid roller 4 for feeding a sheet of paper 10 and a press roller 8 are arranged. Grid roller 4 is formed to have a large diameter portion and a small diameter portion smaller in diameter than the large diameter portion. The sheet of paper 10 pressed by press roller 8 toward grid roller 4 comes to be fed by the large diameter portion. The small diameter portion is formed at a portion that corresponds to a corner portion of the sheet of paper 10. Grid roller 4 is formed of a metal pipe, a resin layer coated on the surface of the pipe, and ceramic particles applied to the resin layer. Thus, a printer apparatus, in which skew of even a dog-eared paper is corrected, is obtained.
