Image Forming Apparatus

An image forming apparatus comprising:

• a plurality of photoconductor drums;
• a plurality of exposure members each configured to expose a corresponding photoconductor drum to light to form an electrostatic latent image on the photoconductor drum;
• a drum supporting member having a pair of side walls spaced apart from each other in an axial direction of the photoconductor drums and configured to support the plurality of photoconductor drums and the plurality of exposure members between the side walls;
• a pair of guide members configured to support the drum supporting member while allowing rectilinear movement of the drum supporting member through an opening formed in the main body such that the drum supporting member is movable from a retracted position in which the drum supporting member is received in a main body of the image forming apparatus, in a direction orthogonal to the axial direction of the photoconductor drums;
• a main body circuit board;
• and
• a relay board configured to output driving signals to the plurality of exposure members,
• wherein the relay board and the main body circuit board are connected by a first cable and the relay board and the plurality of exposure members are connected by second cables, and the relay board is fixed to a first side wall of the pair of side walls of the drum supporting member.
