ABSTRACT:
A guide member is disposed between a transferring section and a fixing section. The guide member has an upstream end and a downstream end with respect to the direction of travel of the recording medium. First and second guide members define a path therebetween in which the recording medium passes to the fixing section. The first guide member is formed with a plurality of ribs formed at intervals and aligned in a direction either transverse or parallel to the direction of travel of the recording medium. The ribs extend substantially from the upstream end to the downstream end and increase in height from the surface of each guide as the downstream end is approached and guide a leading end of the recording medium. The ribs may extent progressively outwardly as the downstream end is approached. The first guide member is supported so that it is pivotal on an axis perpendicular to the direction of travel of the recording medium. The first guide member can be moved between an operative and a non-operative position. The first guide member can receive a voltage of the same polarity as the toner image.
