Inner peripheral end of the shaft, the innermost end of the processed parts 6 and 7, and the shaft flange 10
And the outer diameter fitting portions of the gear flange 20, that is, the steps of the cut portion and the non-machined portion, are butted against each other (the butted surface 27 and the butted surface 29 are butted, the butted surface 28 and (Abutting against the contact surface 29a), the photosensitive drum substrate 1, the shaft 10, and the gear flange 20.
There was no relative tilt between and. Figure 9
FIG. 9 is a diagram showing a state where the photosensitive drum base material shown in FIG. 8 is bent. That is, the shaft 100 is suppressed by chamfering the end portion of the fitting portion 110 and then bending the end portion of the photosensitive drum base material 101. Although not shown, the gear flange side of the photosensitive drum substrate 101 is also bent. As a result, the strength can be increased, and there is no risk that the shaft flange or gear flange will shift in position or fall off.Therefore, even for epoxy adhesives that require curing time, the photosensitive drum can be mounted without waiting for curing. It became possible to immediately send it to the next step such as cleaning or roughening.
