Abstract:
1. An image forming apparatus, comprising: a plurality of image forming units, each of which comprises a photosensitive drum configured to be rotatable about a rotation axis, the plurality of image forming units being arranged to align along an aligning direction orthogonal to a direction of rotation axes of the photosensitive drums; a first frame made of resin and arranged on one side of the plurality of image forming units along the direction of rotation axes, the first frame being configured to support the plurality of image forming units; a first beam made of metal and formed in an elongated shape longitudinally along a direction to intersect with the aligning direction of the plurality of image forming units, the first beam being arranged along a planar face of the first frame and fixed to the planar face of the first frame; and a second beam formed in an elongated shape extending along the aligning direction, the second beam being arranged along the planar face of the first frame to intersect with the first beam and fixed to the planar face of the first frame, wherein rigidity of the first beam is higher than rigidity of the second beam.
