摘要： A nozzle testing device includes: a two-dimensional image sensor to capture an image of a pattern formed on a recording object by discharging ink from a nozzle row while moving the nozzle row and the recording object relative to each other in a direction orthogonal to the nozzle row; a light source unit provided such that regularly reflected light by the pattern forms a regular reflection area in the image of the pattern captured by the two-dimensional image sensor; and a detection unit to analyze the image to detect discharge failure of the nozzles. The regular reflection area is formed in the image such that a dimension in a direction corresponding to the direction of relative movement between the nozzle row and the recording object is greater than a dimension in a direction orthogonal to the direction corresponding to the direction of relative movement in the image.

摘要： An image forming apparatus includes a printing device to print, on a recording medium, a colorimetric pattern including a plurality of colorimetric patches; an imaging device; a conveyor to convey the recording medium in a conveyance direction; and circuitry. The circuitry causes the printing device to form a plurality of marker patterns on a side of the colorimetric pattern and at predetermined intervals in the conveyance direction so that one of the marker patterns is downstream from a first row of the colorimetric patches in the conveyance direction; causes the conveyor to convey the recording medium to position the colorimetric pattern at a reading position by the imaging device based on a distance between the plurality of marker patterns and the colorimetric pattern in the conveyance direction; and causes the imaging device to read the colorimetric pattern on the recording medium.
