摘要： A sheet conveyance device includes a rotary shaft, a conveyance roller, a driving source, and a gear. The gear rotates integrally with the rotary shaft and transmits a driving force from the driving source to the conveyance roller. The gear includes a tooth portion engaging with another gear, a wall surface forming a hole into which the rotary shaft is inserted, a deformable portion, and a pressing part. The deformable portion has a cantilever shape at least partially provided in an area provided with the tooth portion in a gear rotation axis direction. The pressing part protrudes from the wall surface toward the rotation center of the gear, and is elastically deformed by being pressed by the rotary shaft. The pressing part presses the rotary shaft toward the wall surface on a side opposite to the deformable portion in a state where the gear is attached to the rotary shaft.

摘要： A sheet feeding device includes a driving roller, a driven roller rotated by the rotation of the driving roller, a non-conductive feeding guide, a conductive frame, a conductive bearing and an urging member to urge the driven roller toward the driving roller. The feeding guide includes a supporting portion to displaceably support the rotation shaft in an urging direction. The frame includes a positioning portion to position the driven roller in the urging direction by contact with the rotation shaft in a state in which the driving roller is urged by the driven roller.
