ABSTRACT:
In an image forming apparatus, a device for turning a paper of the present invention has a transport roller constantly rotatable in a predetermined direction for paper transport. A reverse transport member is positioned downstream of the transport roller in the predetermined direction, and transports the paper, transported by the transport roller, in the direction opposite to the predetermined direction. A turn guide has a first guide face for guiding the paper toward the transport roller, and a second guide face for guiding in a paper discharge direction the paper being transported by the reverse transport member in the direction opposite to the predetermined direction. The end portion of the first and second guide faces close to the reverse transport member extends in the direction in which the end portion intersects the periphery of the transport roller. Hence, the end portion is angularly retracted by the paper, being guided by the first guide face, to a position coincident with a line tangential to the transport roller. The end of the turn guide is configured such that the first and second guide portions are tapered. The device is miniature and reduces resistance to act on the incoming paper and surely urges it against the transport roller to generate a driving force. As a result, the paper is prevented from being skewed or caught or from jamming the path.
