Sheet separation transport mechanism, and sheet transport device and image forming apparatus including same

摘要

A sheet separation transport mechanism (40) according to the present disclosure includes a sheet feed member (30), a separation member (35), a support member (37), a sheet member (45) and a concave portion (47). The sheet feed member (30) feeds a sheet in a transport direction. The separation member (35) is pressed onto the sheet feed member (30). The support member (37) includes: a separation member retaining portion (37b); and a guide portion (37a) which guides lead edges of a plurality of sheets to the downstream side along the inclined surface. The sheet member (45) is adhered from the guide portion (37a) so as to overlap the separation member (35) and has a frictional coefficient lower than the separation member (35). The concave portion (47) is formed in the shape of a groove in a position of the guide portion (37a) where the sheet member (45) is adhered such that the depth of the concave portion (47) is greater than the thickness of the sheet member (45).
