Title: Image forming method
Inventor: NAKAJIMA YOSHIHIRO
IPC: G03G15/20
Filed: 1989-02-13
Abstract: PURPOSE:To carry out high-density, high-concentration recording employing an electric viscous fluid for a recording body where coloring material is dispersed or dissolved in an insulating solvent and impressing an electric field on recording paper to which the recording body attaches after the recording body is made to adhere to the recording paper. CONSTITUTION:An appropriate pressing means such as a pump supplies the recording body with pressure that cannot jet the recording body by itself from an orifice to an ink jet printer head 6 possessing the orifice. When a piezoelectric vibrator sticking to the upper part of the ink jet printer head 6 is mechanically vibrated, the recording body is jetted out as a liquid drop from the orifice and attaches to the recording paper 3. The recording paper 3 to which the recording body has attached is carried by a carrying roller 4, and the recording body is dried and fixed while the paper passes under an electric field formed by an electrode 1. After drying and fixing, a recorded image on the recording paper 3 never develops blurring.
