Claim:
1. A paper feeding apparatus for an image forming apparatus, the paper feeding apparatus comprising: a first paper feeding roller configured to convey a print medium loaded in a first paper feeding tray; a first one-way rotation transmission member disposed coaxially at the first paper feeding roller and configured to transmit a first one-way rotational force to the first paper feeding roller; a second paper feeding roller configured to convey a print medium loaded in a second paper feeding tray disposed apart from the first paper feeding tray; a second one-way rotation transmission member disposed coaxially at the second paper feeding roller and configured to transmit a second one-way rotational force to the second paper feeding roller; a drive source configured to generate a rotational force to rotate the first and second paper feeding rollers; a first power transmission member disposed between the first one-way rotation transmission member and the drive source, the first power transmission member configured to transmit power of the drive source to the first one-way rotation transmission member; a second power transmission member disposed between the second one-way rotation transmission member and the drive source, the second power transmission member configured to transmit the power of the drive source to the second one-way rotation transmission member; and a conveying roller driven by the second power transmission member, wherein when the drive source rotates in a first direction, the first paper feeding roller conveys the print medium from the first paper feeding tray with the first one-way rotation transmission member, and when the drive source rotates in a direction opposite to the first direction, the second paper feeding roller conveys the print medium from the second paper feeding tray with the second one-way rotation transmission member.
