Abstract
An image forming apparatus operable in a duplex image transfer mode of the present invention stores image data to be transferred and transfers the image data to a recording medium at an image forming section. In the duplex image transfer mode, a reversing section reverses a paper sheet or similar recording medium passed the image forming section and again delivers it to the image forming section. When image data does not have to be transferred to the rear side of the last paper sheet, the last paper sheet carrying an image on its front side is driven out of the apparatus from the halfway point of a reversal path via an outlet path without the intermediary of the image forming section. The apparatus successfully reduces the conveying time.
Claims34
An image forming apparatus for storing image data and providing said image data to a recording medium at an image forming section, said image forming apparatus comprising:
- a reversing section for reversing the recording medium and again delivering said recording medium to the image forming section to thereby form the image data on both sides of said recording medium;
- and
- an outlet path included in said reversing section for directly delivering, when the image data does not have to be transferred to a rear side of a last recording medium, said last recording medium carrying an image on a front side thereof and positioned at said reversing section to an outside of said image forming apparatus without the intermediary of the image forming section,
- wherein the last recording medium is reversed by said reversing section before a second recording medium from the last is delivered to an outside after said second recording medium from the last has been delivered to the outside.
An image forming apparatus for storing image data and providing said image data to a recording medium at an image forming section, said image forming apparatus comprising:
- a reversing section for reversing the recording medium and again delivering said recording medium to the image forming section to thereby form the image data on both sides of said recording medium;
- and
- an outlet path included in said reversing section path, for directly delivering, when the image data does not have to be transferred to a rear side of a last recording medium, said last recording medium carrying an image on a front side thereof and positioned at said reversing section to an outside of said image forming apparatus without the intermediary of the image forming section,
- wherein said reversing section reverses a direction of conveyance of the recording medium from the image forming section and turns over said recording medium, said outlet path being formed at a position which said recording medium delivered from said reversing section passes, and
- wherein said reversing section delivers a trailing edge of a second recording medium from the last and a leading edge of the last recording medium to the outside at an interval smaller than an interval between a trailing edge of another recording medium and a leading edge of a recording medium following said another recording medium.
An image forming apparatus for storing image data and providing said image data to a recording medium at an image forming section, said image forming apparatus comprising:
- a reversing section for reversing the recording medium and again delivering said recording medium to the image forming section to thereby form the image data on both sides of said recording medium;
- and
- an outlet path included in said reversing section path, for directly delivering, when the image data does not have to be transferred to a rear side of a last recording medium, said last recording medium carrying an image on a front side thereof and positioned at said reversing section to an outside of said image forming apparatus without the intermediary of the image forming section,
- wherein said reversing section reverses a direction of conveyance of the recording medium from the image forming section and turns over said recording medium, said outlet path being formed at a position which said recording medium delivered from said reversing section passes,
- wherein after a third recording medium from the last has been conveyed to the image forming section via a registration position, the last recording medium begins to be fed from a recording medium feeding section, and wherein after said last recording medium has been conveyed to said image forming section via said registration position, the second recording medium from the last is delivered from said reversing section to said image forming section.
An image forming apparatus for storing image data and providing said image data to a recording medium at an image forming section, said image forming apparatus comprising:
- a reversing section for reversing the recording medium and again delivering said recording medium to the image forming section to thereby form the image data on both sides of said recording medium;
- and
- an outlet path included in said reversing section path, for directly delivering, when the image data does not have to be transferred to a rear side of a last recording medium, said last recording medium carrying an image on a front side thereof and positioned at said reversing section to an outside of said image forming apparatus without the intermediary of the image forming section, and
- wherein said reversing section delivers a trailing edge of a second recording medium from the last and a leading edge of the last recording medium to the outside at an interval smaller than an interval between a trailing edge of another recording medium and a leading edge of a recording medium following said another recording medium.
An image forming apparatus for storing image data and providing said image data to a recording medium at an image forming section, said image forming apparatus comprising:
- a reversing section for reversing the recording medium and again delivering said recording medium to the image forming section to thereby form the image data on both sides of said recording medium;
- and
- an outlet path included in said reversing section path, for directly delivering, when the image data does not have to be transferred to a rear side of a last recording medium, said last recording medium carrying an image on a front side thereof and positioned at said reversing section to an outside of said image forming apparatus without the intermediary of the image forming section, and
- wherein after a third recording medium from the last has been conveyed to the image forming section via a registration position, the last recording medium begins to be fed from a recording medium feeding section, and wherein after said last recording medium has been conveyed to said image forming section via said registration position, the second recording medium from the last is delivered from said reversing section to said image forming section.
