Abstract:
An image forming apparatus includes a paper dust collecting unit which collects, by application of a voltage, paper dust attached to a sheet, an optical detection unit provided on a downstream side of the paper dust collecting unit in a sheet conveyance direction, which irradiates the sheet with light and receives light via the sheet, a guide member which comes into contact with the sheet to be conveyed to guide the sheet, at least one of light directed toward the sheet from the optical detection unit and light directed toward the optical detection unit from the sheet passing through the guide member, and a control unit which switches a polarity of the voltage to be applied to the paper dust collecting unit and causes the sheet charged through the paper dust collecting unit to be conveyed to the guide member.

Claim (Index 7):
The image forming apparatus according to  claim 1 , wherein the paper dust collecting unit comprises a paper dust collecting roller configured to come into contact with the sheet and rotate to collect the paper dust attached to the sheet and a paper dust collecting portion in which the paper dust collected by the paper dust collecting roller is accumulated.
