Patent number: 6281915Abstract: A recording apparatus of the present invention includes a bearing member for bearing a recording medium having toner and carrier and a backing electrode opposing to the bearing member for electrically attracting the toner on the bearing member. The toner and carrier are charged to opposite polarities. A substrate having a plurality of apertures is provided between the bearing member and the backing electrode. This allows the toner to propel from the bearing member toward the backing electrode. Further, both the toner and carrier have respective volume mean diameters smaller than a diameter of the apertures, and the volume mean diameter of the toner is larger than that of the toner. With the arrangement, the toner will propel through each aperture to form a corresponding image portion, i.e., dot, thereby forming a high quality image without any dot-defect.Type: GrantFiled: March 9, 1999Date of Patent: August 28, 2001Assignee: Minolta Co., Ltd.Inventors: Hirokatsu Shimada, Toshio Yamaki, Koji Uno, Yoshifumi Shibata, Hiroshi Hiraguchi

Patent number: 6231164Abstract: The printing head 50 includes an insulative member 52 in which pluralities of apertures 56 are formed. Doughnut-like first and second electrodes 68 and 70 are disposed around the aperture 56. Pulse voltages V1(P) and V2(P) both having a certain polarity opposite to that of the toner particles are applied to the first and second electrodes 68 and 70, energizing the toner particles 38 to afford propelling thereof. Subsequently, a voltage V2(B) having the same polarity as the charged toner particles 38 is applied to the second electrode 70, forcing radially inwardly to converge the propelling toner particles 38 in the aperture 56. This ensures that a dot and an image both having clear contour can be formed on the sheet 8.Type: GrantFiled: November 20, 1998Date of Patent: May 15, 2001Assignee: Minolta Co., Ltd.Inventors: Yoshifumi Shibata, Toshio Yamaki, Hirokatsu Shimada, Koji Uno, Hiroshi Hiraguchi

Patent number: 6227656Abstract: A print head 50 comprises an insulative sheet member 52 that includes a plurality of apertures 56 arranged in rows. Arranged adjacent to each aperture 56 are first and second electrodes 68 and 70. The first electrode 68 is communicated with a driver 72 while the second electrode 70 is communicated with a driver 76 or 80. By applying first and second pulsating signals with the first and second electrodes, respectively, printing particles on a portion of bearing member 30 that opposes to the electrodes are energized to propel into corresponding aperture. A voltage and/or duration of the pulsating signal is determined according to the distance between the portion of the bearing member and the opposing aperture. Thereby, almost the same amount of printing particles are propelled into each aperture to form the same size dots on the sheet substrate 8.Type: GrantFiled: September 22, 1998Date of Patent: May 8, 2001Assignee: Minolta Co., Ltd.Inventors: Yoshifumi Shibata, Toshio Yamaki, Hirokatsu Shimada, Koji Uno, Hiroshi Hiraguchi
