Abstract:
A sheet conveying apparatus includes: a feeding unit configured to feed a sheet member; a conveying roller that is provided downstream of the feeding unit in a conveying direction, and that is configured to convey the sheet member fed by the feeding unit downstream in the conveying direction; a motor configured to drive the conveying roller. In a state where the conveying roller is conveying a first sheet member that was fed by the feeding unit, if a value of a torque current component of a drive current flowing in a winding of the motor changes from a value greater than or equal to a predetermined value to a value less than the predetermined value, the feeding unit starts feeding of a second sheet member that is to be fed after the first sheet member.
