PURPOSE:To obtain the image recording device which is driven at a low signal voltage and has high reliability by including an ion current modulating means which give a charge in an image shape with an ion current and a transfer means which gives a charge to recording paper which contacts a developer carrier from its reverse surface. CONSTITUTION:An air flow B is generated to transport forcibly ions generated by a corona discharger 8, and an electric signal is applied to a control electrode 7a provided nearby the exit of the air flow to control the passing amount of ions. This charge supplying means 4 gives a charge in the image shape to a toner layer to evade completely the staining of the electrode due to the contact electrostatic charging by a multistylus electrode and the electrostatic charging by ion flow modulation having no air flow. The toner layer is sent to a transfer part and given the charge of the same polarity with toner 3 by a transfer corotron 5 from the reverse side of recording paper 6 while contacting the recording paper 6 to dislocate only image part toner onto the recording paper 6, obtaining a recording image. Consequently, the image corresponding to an electric signal is recorded with the simple constitution, the device is driven at a low signal voltage, and a high-reliability image is obtained. |
