A sheet convey apparatus and a printer having such a sheet convey apparatus have rock arms rockable around a rotational center of a driven roller on which an endless belt is supported. Urging roller attaching plates for supporting the urging roller, a transmission shaft, urging roller driving arms and urging cylinders are attached to the rock arms, and the urging cylinders can abut against the corresponding urging roller driving arms. Urging force releasing springs are connected between the urging roller driving arms and the rock arms. When the urging cylinders are extended, the urging roller is urged against the endless belt, and, when the urging cylinders are retracted, the urging force of the urging roller is released. In this way, a sheet urging force is kept constant to eliminate unevenness of the contact between the sheet and the endless belt, and any streak is prevented from being formed on the sheet.
