ABSTRACT:
An image forming apparatus includes a main casing, a paper-dust collecting roller, a paper-dust removing member, a conveying roller, and an urging member. The paper-dust collecting roller is rotatably supported at a fixed position in the main casing so as to confront a conveying path of a recording medium. The paper-dust collecting roller is configured to collect paper dusts adhering to the recording medium. The paper-dust removing member removes the paper dusts collected by the paper-dust collecting roller. The conveying roller is supported at a position in confrontation with the paper-dust collecting roller across the conveying path. The conveying roller is configured to remove relative to the paper-dust collecting roller. The urging member urges the conveying roller toward the paper-dust collecting roller.
