Abstract
An image forming apparatus according to the present invention comprises a photoconductor drum rotatable around a drum shaft, an exposure unit for forming an image on the drum, a developing unit for supplying a developing agent to the image formed by the exposure unit, thereby forming a developing agent image, a transfer belt for transferring the developing agent image formed by the developing unit to paper, a drive motor having a drive shaft mounted with a coupling into which the distal end portion of the drum shaft is inserted such that the drive shaft and the drum shaft are coaxially connected to each other by means of the coupling, and a plurality of split pieces formed on the drum shaft and/or the coupling and adapted to be elastically deformed in a direction such that the split pieces contract or expand when the drum shaft is inserted into the coupling.
