Abstract
An image forming device includes: a transfer roller; two registration rollers feeding a recording medium to a transfer nip where the transfer roller is in contact with an image bearing member; a transfer conveying-path through which the recording medium is fed from a registration nip formed by the registration rollers to the transfer nip; a lower guide defining a lower side of the transfer conveying-path and having an uppermost portion protruding upwardly at a position upstream of the transfer nip; and a biasing member provided at an upper side of the transfer conveying-path and between the uppermost portion and the registration rollers, and biasing the recording medium downwardly when it is fed through the registration rollers. The biasing member is movable upwardly relative to a pressing force of the recording medium that is fed through the transfer conveying-path.
