Abstract

PURPOSE:To rapidly and accurately control the degree of deflection of ink particles by utilizing an amount of the change of the ink particles by making ink supply to an accumulator a substantially constant flow. CONSTITUTION:In the captioned recording device, while the degree of deflection of charged ink particles Xd (Qj indicates the amount of electric charge of the ink particles mj indicates the mass, vj flying speed, E deflection field strength and K a constant determined by a deflection electrode) is expressed by the equation, in the case of using a fixed displacement pump as a means of ink supply, even if temperature of the ink varies, the mass mj and the flying speed vj of the ink particles are held at almost constant values. And therefore, by detecting the amount of the electric charge Qj of the ink particles and controlling the deflection field strength E by using this value, control of the deflection degree Xd of the ink particles can be ensured. Further, instead of the aforementioned amount of electric charge, Qj, it may be possible to use a value detected as the degree of deflection of the ink particles corresponding to the amount of electricity charged.
