ならないという問題があった。However, in the conventional adhesive applying device, the disk bodies (20), (20) are used.
When gripping the photoconductor drum (W), it is difficult to accurately align the axes, and the held photoconductor drum (W) is eccentric to the disc bodies (20) and (20). As a result, the discharge distance from the discharge port (22) of the nozzle (21) to the inner peripheral surface (W 1 ) of the photosensitive drum (W) varies, so that the adhesive is evenly distributed on the inner surface of the photosensitive drum (W). There is a problem that the coating cannot be applied, and there is a concern that the flange may not adhere properly. Further, in the conventional adhesive applying device, since the nozzles (21) and (21) are rotated, depending on the flow rate of the adhesive, a thread pulling phenomenon is caused at the discharge ports (22) and (22), and it is extended. However, there is a problem in that the discharge ports (22) and (22) must be frequently cleaned because the photosensitive drum (W) may be contaminated.
