Title: Ink jet printer
Inventor: TAKEYAMA HIROYUKI
IPC: B41J2/165
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet printer generating no color mixture between nozzle rows emitting inks of different colors even if wiping cleaning is performed by a wiping member. SOLUTION: Ink repelling regions 37 are formed to the vicinal parts of a large number of emitting nozzles 35 constituting four nozzle rows emitting four color inks of the ink emitting surface of a printing head 34 by using a material making the contact angle of an ink drop larger than 90 deg. and ink-philic regions 38 are formed to regions other than the vicinity of the emitting nozzles, that is, the regions between the nozzle rows by using a material bringing the contact angle of an ink drop to below 90 deg.. Since the potential energy of the inks bonded to the ink repelling regions 37 becomes lower than that of the inks bonded to the ink-philic regions 38, bonded inks 39 are ready to gather to the ink-philic regions 38 low in potential energy as shown by arrows a, b, c, d.  Therefore, even if wiping is performed by a single cleaning blade, the surface of the printing head 34 is cleaned without generating the color mixture of inks.
