ABSTRACT:
An image forming apparatus (100) includes a photoreceptor drum (1), a development unit (2), a pressing member (7), and a vibration absorption member (8). The development unit (2) is disposed adjacent to the photoreceptor drum (1), and supported movably toward and away from the photoreceptor drum (1). The pressing member (7) urges the development unit (2) toward the photoreceptor drum. The vibration absorption member (8) frictionally suppresses the movement of the development unit (2) toward and away from the photoreceptor drum (1). The vibration absorption member (8) attenuates a self-excited vibration of the development unit (2), by suppressing the movement of the development unit (2).
