    摘要: An image forming apparatus is disclosed which reads a test pattern formed by ejecting liquid droplets onto a recording medium to adjust an ejection timing of the liquid droplets. The image forming apparatus includes a reading unit; a relative movement unit; a second detected data obtaining unit; a first detected data obtaining unit; a subtraction processing unit which subtracts a value comparable to a local minimum value of first detected data sets from each of the first detected data sets and second detected data sets; and a signal correction unit which calculates a proportion of the subtracted first detected data sets relative to the subtracted second detected data sets to align a local maximum value of the first detected data sets such that it is generally constant.

    摘要: An image forming apparatus including a first carriage having a first recording head to eject black liquid droplets, a second carriage having a second recording head to eject color liquid droplets and separatably dockable with the first carriage, a position detector to detect a position of the second carriage relative to the first carriage in a state in which the first and second carriages are docked with each other, and a landing position corrector to correct landing positions of liquid droplets ejected from at least one of the first and second recording heads. The landing position corrector holds the position of the second carriage obtained by the position detector as a reference position and adjusts a correction amount for correcting the landing positions based on an amount of shift between the reference position and a present position of the second carriage docked with the first carriage.
