Abstract
A detection device includes a first detection unit that detects a leading edge portion and a trailing edge portion of a medium before the medium is heated, and a second detection unit that differs from the first detection unit and that detects the leading edge portion and the trailing edge portion of the medium after the medium is heated.
Claims6
A detection device comprising:
- a first detection unit that detects a leading edge portion and a trailing edge portion of a medium before the medium is heated;
- and
- a second detection unit that differs from the first detection unit and that detects the leading edge portion and the trailing edge portion of the medium after the medium is heated,
- wherein the first detection unit and the second detection unit detect the leading edge portion and the trailing edge portion of the medium while the medium is not heated during a calibration.

An image forming apparatus comprising:
- a first detection unit that detects a leading edge portion and a trailing edge portion of a medium before the medium is heated;
- a second detection unit that differs from the first detection unit and that detects the leading edge portion and the trailing edge portion of the medium after the medium is heated;
- and
- an image forming unit that forms an image based on detection results obtained by the first detection unit and the second detection unit,
- wherein the first detection unit is disposed downstream of a position upstream of a transfer point, at which the image is transferred to the medium, along a transport passage of the medium by a distance by which the image moves from a formation point, at which the image is formed, to the transfer point, and
- wherein the second detection unit is disposed upstream of the position upstream of the transfer point, at which the image is transferred to the medium, along the transport passage of the medium by the distance by which the image moves from the formation point, at which the image is formed, to the transfer point.

A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:
- performing a first detection of detecting a leading edge portion and a trailing edge portion of a medium before the medium is heated;
- and
- performing a second detection of detecting the leading edge portion and the trailing edge portion of the medium after the medium is heated, the second detection being different from the first detection,
- wherein the first detection and the second detection detect the leading edge portion and the trailing edge portion of the medium while the medium is not heated during a calibration.
