Abstract
A photoconductor drum support structure includes a photoconductor drum that is supported to rotate about a rotation axis; a drum shaft that passes through the photoconductor drum, and is disposed along a rotation axis; a notch formed on the first end in the rotation axis direction of the drum shaft; a drum frame that retains the photoconductor drum to rotate, the drum frame including an opening that is formed on the first end in the rotation axis direction on the drum frame, and enables insertion of the first end of the drum shaft, an engaging portion that is engaged with the notch formed on the drum shaft inserted into the opening, and that regulates displacement of the drum shaft towards the second end.
