First Claim
Patent Images
1. An image forming apparatus comprising:
- an image forming portion to form a toner image on a recording media;
a fixing unit to clamp and convey said recording media and fixing said toner image;
an ejection unit installed on a downstream side of said fixing unit to eject said recording media;
an intra-body paper ejection unit to stack said recording media ejected from said ejection unit; and
a control unit to set said ejection unit as an intra-body paper ejection mode to at a first rate when a relay unit to relay said recording media toward an option, while to set said ejection unit as an option mode to drive at said first rate when said relay unit is mounted and said recording media is ejected toward said option, and to drive said ejection unit at a second rate faster than said first rate when said relay unit is mounted, said recording media pass a fixing unit and said recording media is ejected toward said intra-body paper ejection unit.

Abstract
A drive unit for changing the driving rate of paper ejection rollers for ejecting sheets of paper after fixing is installed, and an image forming apparatus has an option, and when ejecting the sheets of paper to an intra-body paper ejection unit, after the sheets of paper pass a fixing device, the paper ejection rate of paper ejection rollers 24 is increased, and the ejection force of the sheets of paper P is increased, and paper jamming at the time of paper ejection to the intra-body paper ejection unit is prevented.

5. A paper ejection method of an image forming apparatus comprising:
-
detecting whether a relay unit is mounted to convey recording media in an optional direction after said recording media is fixed, first mode setting a paper ejection mode to an intra-body paper ejection mode for ejecting said recording media to an intra-body paper ejection unit at a first rate when non-mounting of said relay unit is detected at said detecting, and second mode setting a paper ejection mode to an option mode for ejecting said recording media at said first rate when mounting of said relay unit is detected at said detecting and said recording media is ejected toward said relay unit, and for ejecting said recording media at a second rate faster than said first rate when mounting of said relay unit is detected at said detecting, said recording media pass a fixing unit and said recording media is ejected toward said intra-body paper ejection unit. - View Dependent Claims (6, 7, 8)
