Abstract
A sheet member supply device (40) of an image forming apparatus (1) includes a sheet member stacking plate (43) in which sheet members (S) are stacked on the upper surface, a pickup roller (51) which makes contact with, from above, the uppermost layer of the sheet members (S) stacked on the sheet member stacking plate (43), a stacking plate displacement mechanism (44) which displaces the sheet member stacking plate (43) upward, a motive power transmission mechanism (60) which transmits motive power obtained from a drive source (45) to the stacking plate displacement mechanism (44) and a paradox planetary gear mechanism (65) which is provided in the motive power transmission mechanism (60). In this way, with a simple configuration, it is possible to reduce the unintentional downward displacement of the stacking plate.
