An object of the present invention is to provide an image reading apparatus that has a simple mechanism for ejecting dust collected from a transparent member by a cleaner to the outside, thereby preventing stripe noise from being mixed into read image data. Disclosed is an image reading apparatus, wherein while an automatic document feeder is feeding a document (D) such that the document (D) passes over a reading glass (40), an image of the document is optically read at a reading position (A). Above the reading glass (40), a brush type cleaner (45) is disposed to face to the reading position (A) and to be capable of rotating. At a downstream position from the cleaner (45) with respect to a document feeding direction (B), a duster (46) is disposed for a dusting operation to remove dust from the cleaner by slapping against the cleaner (45). Before the leading edge of the document (D) comes to the reading position (A), the cleaner (45) rotates to clean the reading glass (40), and while the document (D) is covering the reading glass (40), the duster (46) slaps against the cleaner (45) to dust the cleaner (45). |
