In a sheet feeding device (3), a feeding roller (51) is driven and rotated to feed a sheet (P) in a conveying direction of a sheet conveying path (300) and a drive transmission mechanism (5F) transmits rotation drive force generated in a driving portion (500) to the feeding roller (51). In this mechanism, a drive input gear (55) having an inner space (551) is arranged on a rotation axis (59) supporting the feeding roller (51) rotatably so as to rotate by the rotation drive force. A drive transmission gear (53) arranged between the feeding roller (51) and drive input gear (55) on the rotation axis (59) rotates and becomes slide-movable along the rotation axis (59) between a first position transmitting the rotation drive force to the feeding roller (51) and a second position cutting off the transmission of the rotation drive force to the feeding roller (51) by the rotation drive force from the drive input gear (55) to transmit the rotation drive force to the feeding roller (51). |
