Recording medium conveying mechanism and image forming apparatus having the same

摘要

A recording medium conveying mechanism includes a conveying guide, a guide member, and a rotating mechanism. The conveying guide conveys recording paper to a nip zone between a mountable/demountable intermediate transfer unit and a secondary transfer roller. The guide member acting as a part of the conveying guide is rotated by the rotating mechanism so that a tip thereof is disposed up to a position just adjacent to the nip zone when the intermediate transfer unit is mounted in the apparatus main body. When the intermediate transfer unit is mounted/demounted in/from the apparatus main body, the guide member is rotated up to a position at which the tip thereof does not exceed an arrangement position of the intermediate transfer belt portion in a conveying direction of the recording paper, in a movement direction of the intermediate transfer unit during the mounting/demounting.

主权项

1. A recording medium conveying mechanism comprising:
a conveying guide whose tip runs up to a nip zone between an intermediate transfer belt mounted on an intermediate transfer unit and a secondary transfer roller disposed to face the intermediate transfer belt beyond an arrangement position of a portion of the intermediate transfer belt at an uppermost stream side in a conveying direction of a recording medium, and which guides movement of the recording medium conveyed toward the nip zone; a rotating mechanism; and a guide member that is a portion of the conveying guide having the tip, is rotated by the rotating mechanism when the intermediate transfer unit is mounted/demounted relative to an apparatus main body of an image forming apparatus, and is rotated toward a position at which the tip does not exceed the arrangement position of the intermediate transfer belt portion in the conveying direction of the recording medium when the intermediate transfer unit is mounted/demounted, in a movement direction of the intermediate transfer unit during the mounting/demounting.
