A sheet conveying device includes: first, second and third rollers, a conveying member, a frame, a first pressing member, and a force-generating unit. The first and second rollers rotate while nipping the sheet therebetween. The third roller and the conveying member nip the sheet therebetween. The frame is elongated parallel to an axis about which the third roller rotates and supports the third roller. The first pressing member applies a first pressing force to an axial center of the first roller to press the first roller toward the second roller and applies a reaction force of the first pressing force to the frame to press the frame in a direction toward the conveying member. The force-generating unit generates a nipping force for nipping the sheet between the third roller and the conveying member and applies an urging force to the frame in a direction away from the conveying member.
