Abstract
An image forming apparatus includes an image forming device and circuitry. The image forming device forms an image. The circuitry corrects an amount of deviation based on a pattern formed by the image forming device, changes a magnification of the pattern, and calculates the amount of deviation based on the magnification.
Claims15
An image forming apparatus comprising:
- an image forming device configured to form an image with a set magnification;
- a sensor configured to detect a pattern formed by the image forming device;
- and
- circuitry configured to:
- correct an amount of deviation in color of the image based on the pattern formed by the image forming device and detected by the sensor;
- change both a magnification of the pattern and the set magnification of the image;
- and
- calculate the amount of the deviation based on the changed magnification of the pattern and the changed set magnification of the image.
