Abstract:
1. A data generating device generating reaction liquid ejecting data which is used in an image forming device which forms an image by ejecting an ink drop on the basis of ink drop ejecting data and ejecting a reaction liquid drop, which reacts with the ink drop, on the basis of the reaction liquid ejecting data, wherein the data generating device generates the reaction liquid ejecting data pixel by pixel on the basis of ink drop ejecting data of a pixel of interest, an error which was diffused to the pixel of interest from a peripheral pixel when reaction liquid ejecting data was generated previously for the peripheral pixel, and a predetermined ratio of a reaction liquid amount to an ink amount, and the data generating device carries out, for each pixel of interest, adding the predetermined ratio and the diffused error in accordance with the ink drop electing data of the pixel of interest, generating the reaction liquid ejecting data of the pixel of interest in accordance with results of comparison of a threshold value and a sum of the predetermined ratio and the diffused error, and diffusing a difference between the sum and the reaction liquid ejecting data to a peripheral pixel as the error.
