Image forming apparatus and image forming method

摘要

An image forming apparatus includes: an image forming unit that forms a pattern image for image quality adjustment on an image carrier; a detection unit that detects the pattern image for the image quality adjustment; an image quality adjustment control unit that controls an image quality adjustment process in accordance with a result of detection of the detection unit; a reception unit that receives a color mode selected from among a plurality of kinds of color modes; and a calculation unit that calculates a total pattern length so that a total length of the pattern image for the image quality adjustment in a sub-scanning direction is equal in any of the color modes, wherein the image forming unit forms the pattern image for the image quality adjustment so that the total length of the pattern image for the image quality adjustment is equal to the calculated total pattern length.

1. An image forming apparatus comprising:
an image former that forms a pattern for positional deviation correction on an image carrier; a detector that detects the pattern for positional deviation correction; a controller that controls a positional deviation correction process in accordance with a result of detection of the detector; a receiver that receives a color mode selected from among a plurality of color modes, each having a different number of colors used for forming the pattern; and circuitry configured to calculate a total pattern length so that a total length of the pattern for positional deviation correction in a sub-scanning direction is equal in any of the color modes, wherein the image former forms the pattern for positional deviation correction including the number of colors corresponding to the selected color mode so that the total length of the pattern for positional deviation correction is equal to the calculated total pattern length.
