摘要： In the present invention, an electrostatic latent image is formed on the surface of an image carrying member, while ink having a tack value of not less than one is used as ink in an ink developing device. The ink is held in an ink carrying member. The ink held in the ink carrying member is brought into contact with the surface of the image carrying member to supply the ink to the electrostatic latent image formed on the surface of the image carrying member, to form an ink image on the surface of the image carrying member. The ink image is transferred onto a recording medium from the surface of the image carrying member by a transfer device.

摘要： An electrostatic recording apparatus 1 for forming an electrostatic image on an electric charge carrying member 2 includes a photoelectric transfer member 14, a pair of bias electrodes 12, 13, an electric power supply 17, a floating electrode 16 and an exposure means 8. The photoelectric transfer member 14 which generates carrier when being exposed to light is interposed between the bias electrodes 12, 13. One of the bias electrodes 12 is transparent. The electric power supply 17 applies a voltage between the bias electrodes 12, 13. The floating electrode 16 has a first area which comes into contact with the photoelectric transfer member 14 and a second area which is opposed to the electric charge carrying member 2. The floating electrode 16 is in no electrical connection with the bias electrodes 12, 13. The exposure means 8 exposes the photoelectric transfer member 14 through the transparent bias electrode 12 so that a carrier is generated in the photoelectric transfer member 14, thereby an electric discharge is caused from the second area of the floating electrode 16 to the electric charge carrying member 2 to form an electrostatic image on the electric charge carrying member 2.
