    摘要： An image forming apparatus includes an apparatus main body part and a sheet feed unit installed below the apparatus main body part, which include connector parts electrically connecting the apparatus main body part and sheet feed unit. The connector part at a side of the apparatus main body part includes a window; a first connector main body visible through the window and having an electrical connection port facing to the sheet feed unit; a connector cover covering openably/closably the electrical connection port of the first connector main body; and a biasing member biasing the first connector main body downwardly. The connector part at a side of the sheet feed unit includes a second connector main body positioned below the first connector main body. The first connector main body is pressured downwardly with respect to the connector cover by the biasing member, when the connector cover is closed.

    摘要： A sheet transport apparatus includes: a first motor and a second motor; a first roller configured to: rotate upon receiving motive power from the first motor; and transport a sheet in a predetermined transport direction; a second roller which is provided on a downstream side of the first roller in the transport direction and which is configured to: rotate upon receiving motive power from the second motor while nipping the sheet transported by the first roller at a nip position; and transport the sheet further downstream in the transport direction; and a controller. The controller includes a motor control unit configured to perform a first process for rotating the first roller and a second process for rotating the second roller; and a first reaction-force estimating observer configured to calculate a first estimated value which is an estimated value of a reaction force acting on the first motor.

    摘要： Provided are a sheet feeding device and an image forming apparatus for feeding small-size sheets without causing skew and paper jamming. On a downstream side of far-side and near-side side regulating members in a sheet feeding direction, far-side and near-side auxiliary side regulating members are provided so as to be movable in a width direction. When each of sheets has a length capable of being regulated by the far-side and near-side side regulating members in the width direction, the far-side and near-side auxiliary side regulating members are moved to retreat positions. When a sheet has a length shorter than the length capable of being regulated by the far-side and near-side side regulating members in the width direction, the far-side and near-side auxiliary side regulating members are moved to protruding positions, at which they protrude in the width direction with respect to the far-side and near-side side regulating portions.
