Ink jet recording method

The ink jet recording method allows an electrostatic force to act on an ink composition containing at least charged particles containing a colorant and a dispersion medium to form a thread of the ink composition, and divides the thread into small portions to eject ink droplets on a recording medium....

Beschreibung
Zusammenfassung:	The ink jet recording method allows an electrostatic force to act on an ink composition containing at least charged particles containing a colorant and a dispersion medium to form a thread of the ink composition, and divides the thread into small portions to eject ink droplets on a recording medium. A first average concentration of the charged particles contained in the thread from its tip end portion to its central portion is higher than a second average concentration of the charged particles contained in a whole thread. And/or, a first force acting on the charged particles contained in the thread is made larger than a second force obtained by subtracting the first force acting on the charged particles contained in the thread from a second force acting on a whole thread.
