Title: Recorder and recording method
Inventor: OKI YASUSHI
IPC: B41J2/01
Filed: 2000-04-24
Abstract: PROBLEM TO BE SOLVED: To lessen the adverse effect of an electric field for holding recording material on the behavior of an ink drop ejected from a recording head. SOLUTION: Conduction of a heater for ejecting an ink drop from an ink jet head is started at the rising timing of an ejection reference signal.
