Abstract
An image forming apparatus, in which an image forming method is performed, includes an image forming device to form an image on a recording medium, a reading device to scan the recording medium having a mark and generate a scanned image, and circuitry to calculate a correction value to adjust a position of the image to be formed on the recording medium, based on the scanned image. The circuitry calculates the correction value to adjust a position of an image to be formed on a second face of the recording medium based on a first scanned image generated from a first face of the recording medium, within a period from when the first scanned image is generated from the first face to when the image starts to be formed on the second face.
Claims18
An image forming apparatus comprising:
- an image forming device configured to form an image on a recording medium;
- a reading device configured to scan the recording medium having a position detection mark on the recording medium as the image and generate a scanned image;
- and
- circuitry configured to calculate a correction value to adjust a position of the image to be formed on the recording medium, based on the scanned image,
- the reading device being configured to generate a first scanned image from a first face of the recording medium,
- the circuitry being configured to calculate the correction value to adjust a position of an image to be formed on a second face of the recording medium based on the first scanned image generated from the first face of the recording medium, within a period from when the first scanned image is generated from the first face of the recording medium to when the image starts to be formed on the second face of the recording medium.
An image forming apparatus comprising:
- an image forming device configured to form an image on a recording medium;
- a fixing body configured to fix the image formed on the recording medium to the recording medium;
- a branching portion configured to change a direction of the recording medium on which the image is formed, between a direction toward an outside of the image forming apparatus and a direction to a passage conveying the recording medium in a different direction from the direction toward the outside of the image forming apparatus;
- a reading device configured to scan the recording medium having a position detection mark on the recording medium as the image and generate a scanned image,
- the reading device being disposed between the fixing body and the branching portion in a sheet conveying direction of the recording medium;
- and
- circuitry configured to calculate a correction value to adjust a position of the image to be formed on the recording medium, based on the scanned image.
An image forming method performed by an image forming apparatus, the image forming method comprising:
- forming an image on a recording medium;
- scanning a first face of the recording medium having a position detection mark on the recording medium;
- generating a first scanned image from the first face of the recording medium;
- and
- calculating a correction value to adjust a position of an image to be formed on a second face of the recording medium based on the first scanned image generated from the first face of the recording medium, within a period from when the first scanned image is generated from the first face of the recording medium to when the image starts to be formed on the second face of the recording medium.
An image forming apparatus comprising:
- an image forming device configured to form an image on a recording medium;
- a drying device configured to dry the image formed on the recording medium to the recording medium;
- a branching portion configured to change a direction of the recording medium on which the image is formed, between a direction toward an outside of the image forming apparatus and a direction to a passage conveying the recording medium in a different direction from the direction toward the outside of the image forming apparatus;
- a reading device configured to scan the recording medium having a position detection mark on the recording medium as the image and generate a scanned image, the reading device being disposed between the drying device and the branching portion in a sheet conveying direction of the recording medium;
- and
- circuitry configured to calculate a correction value to adjust a position of the image to be formed on the recording medium, based on the scanned image.
