1. An image forming apparatus, comprising:
a plurality of image forming units, each of which comprises a respective photosensitive drum configured to be rotatable about a rotation axis and a developer device configured to supply a developer agent to the respective photosensitive drum, the plurality of image forming unit being aligned along an aligning direction, the aligning direction being orthogonal to an axial direction of the rotation axes of the photosensitive drums; a pair of frames arranged to face each other along the axial direction across the plurality of image forming units, the pair of frames being configured to support the plurality of image forming units; an optical scanner arranged on one side of the plurality of image forming units in an orthogonal direction orthogonal to the aligning direction and to the axial direction, the optical scanner being configured to emit exposure light to the plurality of photosensitive drums; a first connecting frame made of metal and formed to be hollow providing a first space therein, the first connecting frame being coupled to the pair of frames at both ends thereof along the axial direction and being configured to accommodate the optical scanner in the first space, the first connecting frame being disposed above the plurality of image forming units in the orthogonal direction; and a second connecting frame made of metal and arranged below the plurality of image forming units in the orthogonal direction, the second connecting frame being formed to be hollow providing a second space therein, the first space being formed separately from the second space, the second connecting frame extending in the axial direction between and coupling the pair of frames at both ends thereof along the axial direction, the second connecting comprising an upper portion extending between and connecting the pair of frames, wherein the second connecting frame and the pair of frames are configured to enclose a power board within the second space such that a top surface of the power board is disposed lower, in the orthogonal direction, than a bottom surface of the upper portion of the second connecting frame, the power board being configured to supply power to electrically movable components of the image forming apparatus. |
