Abstract
To provide an image forming apparatus capable of achieving both correction accuracy of skew correction and minimization of a margin between images. A color shift amount calculator that calculates a color shift amount, and a first skew correction controller and a second skew correction controller that control skew correction of color shift are included. The first skew correction controller controls first skew correction by a mechanical operation by the image former on the basis of a first color shift residual target value set in advance. The second skew correction controller controls second skew correction, by image processing, of the color shift after the control by the first skew correction controller on the basis of a second color shift residual target value set in advance.
Claims13
An image forming apparatus that forms an image of a plurality of colors on a recording material, the image forming apparatus comprising:
- an image former that forms the image on the recording material;
- and
- a hardware processor that controls image formation by the image former and skew correction in the image formation,
- wherein:
- the hardware processor includes:
- a color shift amount calculator that calculates a color shift amount from a color shift of an image of each color in the image former, and
- a first skew correction controller and a second skew correction controller that control the skew correction of the color shift,
- the first skew correction controller controls a first skew correction by a mechanical operation by the image former based on a first color shift residual target value set in advance, and
- the second skew correction controller controls a second skew correction, by image processing, of the color shift after the control by the first skew correction controller based on a second color shift residual target value set in advance.
