Sheet feeder and image forming apparatus incorporating same

摘要

A sheet feeder, which is included in an image forming apparatus, includes a sheet bypass member openably closable to one side surface of a body of the image forming apparatus, a pickup roller to feed and convey a sheet loaded on the sheet bypass member, and an arm to hold the pickup roller and to open and close with the pickup roller. The arm includes a contact portion extending in a shape of projection toward an upstream side from the pickup roller in a sheet conveying direction of the sheet bypass member. As the sheet bypass member is rotated upward to be closed and stored to the side surface of the body, the contact portion of the arm contacts the sheet bypass member to rotate the arm upward to cause the sheet bypass member to approach to the side surface of the body.
