Title: image forming device
Inventor: NEMOTO SHIORI
IPC: G03G21/16
Filed: 2021-06-16
Abstract: To provide an image forming device with which, even when a relay duct is disposed while being bent with a large curvature, ambient air sent by a fan passes through the relay duct with a desired air flow.SOLUTION: As a relay duct that guides ambient air sent by a fan, bellows-shaped flexible tubes 183a-183d having a number of projections formed on their outer circumferential surfaces are used. When these flexible tubes 183a-183d are bent, they are restricted from being bent by the projections on the inside of the bending (compression side) and can hardly be folded. Therefore, even when the flexible tubes 183a-183d are bent, they can retain the size of the cross section as compared with the situation before the bending, and can guide the ambient air without a change in air flow per unit time. Therefore, use of these flexible tubes 183a-183d makes it possible to easily realize an improvement in the freedom of design of a developing device and the relay duct.SELECTED DRAWING: Figure 5
