A mechanism of a cleaning blade squeaking noise due to a friction between a photoreceptor drum and a cleaning blade in a laser printer is presented in this paper. Although this problem has been known for many years, the details of oscillation mechanism is not clarified, so we have not found out the fundamental solution yet. In order to clarify the mechanism, at first, we took notice of the peculiar features of this noise in an actual machine. Then, we proposed a theoretical model based on a multi freedom coupled model, which can explain the above features of this noise. Finally, we clarified that the oscillation is one of a coupled mode flutter.
