Abstract
A printer includes an image forming unit configured to form an image on a sheet by an electrophotographic method, and a recording unit configured to record an image on a sheet by an inkjet method. An image recording position of the recording unit is located above an image forming position of the image forming unit.
Claims32
A printer comprising:
- a photosensitive drum on which a toner image to be transferred onto a sheet is formed on a face of the photosensitive drum;
- and
- a recording head configured to eject ink onto a sheet,
- wherein the recording head is located above the photosensitive drum,
- the photosensitive drum is configured to form the image on the sheet conveyed along a first path,
- the recording head is configured to record the image on the sheet red along a second path,
- the printer further comprises a reverse roller that is provided on the first path, disposed downstream of the photosensitive drum in a conveyance direction, configured to convey the sheet to both a downstream side and an upstream side in conveyance direction,
- the first path is connected to the second path at a connection position between the photosensitive drum and the reverse roller on the first path,
- the reverse roller is configured to convey the sheet to the downstream side in the conveyance direction and then convey the sheet to the upstream side in the conveyance direction so as to convey the sheet to the second path, and
- the recording bead is disposed above the reverse roller.

- and
- a recording head configured to eject ink onto a sheet,
- wherein the recording head is located above the photosensitive drum,
- the photosensitive drum is configured to form the image on the sheet conveyed along a first path,
- the recording head is configured to record the image on the sheet conveyed along a second path,
- the printer further comprises a reverse roller that is provided on the first path, disposed downstream of the photosensitive drum in a conveyance direction, configured to convey the sheet to both a downstream side and an upstream side in the conveyance direction,
- the first path is connected to the second path at a connection position between the photosensitive drum and the reverse roller on the first path,
- the reverse roller is configured to convey the sheet to the downstream side in the conveyance direction and then convey the sheet to the upstream side in the conveyance direction so as to convey the sheet to the second path,
- the first path is connected to a return path at a position between the photosensitive drum and the reverse roller on the first path, and the return path is a path for returning the sheet to a position upstream of the photosensitive drum on the first path, and
- the reverse roller conveys the sheet to
- the return path by conveying the sheet to the upstream side in the conveyance direction based on a determination that a trailing end of the sheet is located at a first position on the first path, or
- the second path by conveying the sheet to the upstream side in the conveyance direction based on a determination that a trailing end of the sheet is located at a second position that is a position different from the first position on the first path.
