A sheet conveyor device includes a conveyor that conveys a sheet along a conveyance path in a conveying direction, a sheet stack portion that receives the sheet conveyed by the conveyor, and a conducting member. The conveyor includes an ejection roller that ejects the sheet to the sheet stack portion. The conducting member includes a contact portion, disposed along the conveyance path downstream of the ejection roller, which comes into contact with the sheet conveyed by the conveyor, and a discharge portion that discharges static electricity transferred to the contact portion by contact between the sheet and the contact portion.
