PROBLEM TO BE SOLVED: To obtain a cleaning device by which soiling inside an image forming device due to dust is surely prevented even in the case that a sealing performance is deteriorated at a durable use time. SOLUTION: A suction duct 3 for generating air stream in a sucking direction inside a duct and a ventilating duct 13 generating the air flow in a blowing-out direction in the duct are provided on the upper and lower sides of a cleaning unit 2, so that the air stream flowing from the duct 13 to the duct 3 is generated at a part where the cleaning unit 2 and a photoreceptive drum 1 are opposed to each other. Then, the recovery of the dust is executed while suppressing the blowing-out of the dust from the cleaning unit 2. Thus, the soiling at the inside of the device caused by the dust is prevented even in the case that the sealing performance is lowered at the durable use time, and also the life of the filter 4 is extended because the blowing-out of the dust is suppressed, so that the maintenance property of the cleaning device is improved. |
