An image forming apparatus (10) comprises a feeding mechanism (110) that comprises a driving source (101) configured to rotate a first shaft (102) around the first shaft (102), a transmission mechanism (113) configured to transmit rotation of the first shaft (102) in a first direction (R1) to a second shaft (103) and not to transmit rotation of the first shaft (102) in a direction (R2) opposite the first direction (R1) to the second shaft (103); a roller (111) fixed to the second shaft (103) and configured to feed a sheet from a stack (50) of sheets by rotating around the second shaft (103); and a releasing member (119) fixed to the second shaft (103); and a holding mechanism (120) configured to hold the feeding mechanism (110) with the roller (111) away from the stack (50), wherein the releasing member (119) is configured to release the hold on the feeding mechanism (113) by the holding mechanism (120) when the transmission mechanism (113) transmits the rotation of the first shaft (102) to the second shaft (103). |
