Abstract:
1. An image forming apparatus comprising: a plurality of photoconductor drums; a drum supporting member having a pair of side walls disposed opposite to each other in an axial direction of the photoconductor drums and configured to support the photoconductor drums between the side walls; 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 plurality of development cartridges supported by the drum supporting member and each including a developer receptacle containing developer, and a development roller configured to supply developer contained in the developer receptacle to the photoconductor drum; a belt disposed below and opposite to the photoconductor drums; a pair of guide members configured to support the drum supporting member while allowing rectilinear movement of the drum supporting member between a retracted position in which the drum supporting member is received in a main body of the image forming apparatus and a pull-out position to which the drum supporting member is moved from the retracted position and pulled out from the main body through an opening formed in the main body; and a main body circuit board provided in the main body and connected to the exposure members via a cable, wherein when the drum supporting member is in the pull-out position, the development cartridges are detachable from the drum supporting member from above in a detachment direction, wherein the main body circuit board is disposed above and opposite to the development cartridges when the drum supporting member is in the retracted position, and wherein the cable extends outward in the axial direction beyond the photoconductor drums.
