A medium conveying apparatus comprising:

• feed roller pairs spaced and located in a direction perpendicular to a medium conveying direction, to separate and feed a medium;
• and
• conveying roller pairs each including a first conveying roller and a second conveying roller, and respectively spaced and located on a downstream side of the feed roller pairs in the medium conveying direction, and spaced and located in the direction perpendicular to the medium conveying direction, wherein
• for each of the conveying roller pairs,
• a diameter of an outer end in the direction perpendicular to the medium conveying direction of each of the first conveying roller and the second conveying roller is larger than a diameter of an inner end in the direction perpendicular to the medium conveying direction of said each of the first conveying roller and the second conveying roller, and
• a total D of a difference between the diameter of the outer end and the diameter of the inner end of the first conveying roller and a difference between the diameter of the outer end and the diameter of the inner end of the second conveying roller is in a range of 0.06 to 1.00 mm.
