Abstract: An ink jet recording apparatus is disclosed, which apparatus has a pressure chamber that holds an ink liquid, and a nozzle communicating with the pressure chamber for discharging the ink liquid when pressure is applied to the pressure chamber. The pressure chamber has a diaphragm disposed therein. A piezoelectric element made of a monocrystalline or polycrystalline piezoelectric member highly oriented along a polarization axis showing perovskite structure, and mainly composed of lead zirconate titanate or barium titanate, is used to vibrate the diaphragm. When a specified voltage is applied to the piezoelectric element, it causes the ink liquid in the pressure chamber to be discharged into a recording medium at the front side of the nozzle.

Abstract: According to a conventional one-time transfer type color electrophotographic method, since used is a color toner by which the maximum image density can first be obtained by overlapping of 4 to 6 layers, there are problems that the color tone of a mixed color image formed by piling up color-different toner images one after another varies and color irregularity occurs. On the other hand, according to the present invention, by using a color toner whereby the maximum image density of the toner can be attained with one toner layer, the aforementioned problems can be eliminated, and the reproduction of the mixed color image can be achieved by the one-transfer system. In addition, according to the present invention, it is possible to reproduce a clear full-color image with gradation.

Abstract: A charging process, an exposure process, and a development process are performed to form a toner image on a photosensitive member for each of a plurality of different colors. The toner images for the respective colors form a composite color image. Second color toner image forming processes are effected subsequently to first color toner image forming processes. The first color charging process charges the photosensitive member to a first potential. The second color charging process charges the photosensitive member to a second potential. The second potential is set equal to or lower than the first potential. The composite color image is transferred to a sheet.

Abstract: Disclosed is a color electrophotographic method of forming a plurality of images of different colors on a photosensitive medium by repetitions of a series of operations including steps for charging, exposure and development. An exposure of photosensitive medium is conducted to form an electrostatic latent image adjacent to a first toner image which has been formed in the previous process with a non-image are provided at the boundary of the first toner image. The difference in potentials between the toner image and the adjacent image is thereby eliminated, thus preventing scattering of toner particles. This results in a clear color print the colors of which are not blurred and of high purity.
