Disclosed herein is a fine and thick wiring drawn at high speed in such a manner that a region on the substrate, on which region the liquid droplet is scheduled to impact, is heated beforehand, and that immediately after the impact of the liquid droplet on the substrate, the liquid droplet is promptly solidified so as thereby to suppress the spread of the liquid droplet due to the wettability of the liquid droplet to the substrate, and also to suppress the clogging of the nozzle due to the heating of the substrate. Thereby, even in the case where a liquid droplet having a larger volume than before is used, high-speed drawing of a thick and fine wiring having a line width approximately equal to the liquid droplet size is realized independently of the substrate material.

A gradation patch image Ip used for determination of tone characteristics of an apparatus is progressively varied in the tone level thereof from the maximum tone level (level 255) to the minimum tone level (level 0). The gradation patch image is either a toner image continuously and consistently varied in the tone level thereof or a toner image having the tone levels varied stepwise at a smaller pitch than a width of a detection region of a patch sensor. In density detection of such a gradation patch image Ip, toner image densities at portions on either sides in the detection region of the patch sensor are canceled each other out by averaging and hence, only a toner image density substantially at the center of the detection region can be obtained.
