    摘要： An image forming apparatus contains an ink having a dynamic surface tension of from 30 to 50 mN/m at a life time of 15 msec at 25 degrees C., a container containing the ink and a head configured to discharge the ink to a fabric including a first fabric containing synthetic fiber in an amount of more than 50 percent by mass and a second fabric containing natural fiber in an amount of 50 percent by mass or greater, the head including a nozzle surface, wherein a first distance between positions of two consecutive droplets of the ink discharged from the head on the first fabric is shorter than a second distance between positions of two consecutive droplets of the ink discharged from the head on the second fabric.

    摘要： An ink set is provided including a first ink containing a polyvalent metal ion and a second ink containing a copolymer having a structural unit represented by the following general formula (1): wherein R1 represents hydrogen atom or a methyl group, and R2 represents one linking group or a combination of two or more linking groups selected from a group consisting of the following linking groups: —COO—, —OCO—, —O—, —NHCONH—, NR3CO— (R3 represents hydrogen atom or an alkyl group having 1 to 6 carbon atoms), an alkylene group having 1 to 12 carbon atoms, an alkyl ether group having 1 to 12 carbon atoms, and —NR4- (R4 represents hydrogen atom or an alkyl group having 1 to 6 carbon atoms).
