Patent number: 8185010Abstract: Cleaning performance of a cleaning pad for cleaning a charging wire is maintained so that the charging voltage of an image carrier by a charging wire is stabilized. A charging wire cleaning apparatus is provided with a cleaning pad for cleaning a charging wire which charges an image carrier, a slider which is a supporting body for supporting the cleaning pad, and a screw shaft which is a moving mechanism for reciprocating the slider in parallel to the charging wire. When the slider is at a predetermined position of the reciprocation range, the cleaning pad and the charging wire are separated, and the cleaning pad is adapted to be shifted with respect to the charging wire in this state.Type: GrantFiled: September 2, 2008Date of Patent: May 22, 2012Assignee: Sharp Kabushiki KaishaInventors: Masato Kuze, Hirokazu Yamauchi, Toshiki Takiguchi, Kazuhiro Matsuyama, Hiroyuki Murai

Patent number: 8121530Abstract: In an image forming method, an electrostatic latent image formed on a surface of a photoreceptor is developed into a developer image with a developer, and a printing paper transported on a transfer belt is brought into contact with the surface of the photoreceptor so as to transfer the developer image onto the printing paper. The printing paper is transported in a proper transport direction, in which a projection generated in one direction on the printing paper as a result of cutting the printing paper in a printing paper manufacturing process does not face a surface of the transfer belt at a leading edge of the printing paper being transported on the transfer belt. In this way, even in the presence of the projection generated when the printing paper is cut, the printing paper naturally strips off from the surface of the photoreceptor, thereby preventing toner contamination caused by a striping claw in contact with the leading edge of the printing paper.Type: GrantFiled: February 9, 2011Date of Patent: February 21, 2012Assignee: Sharp Kabushiki KaishaInventors: Toshiki Takiguchi, Hiroyuki Murai, Masato Kuze, Yuji Kumagai

Patent number: 7933527Abstract: In an image forming apparatus, an electrostatic latent image formed on a surface of a photoreceptor is developed into a toner image. A printing paper transported on a transport belt is brought into contact with the surface of the photoreceptor and an electric field is applied to the printing paper from a rear surface of the transport belt by a transfer roller to transfer the toner image onto the printing paper. The transfer roller applies different levels of electric field to the printing paper, so that a predetermined transfer electric field is applied to a region other than a leading edge of the printing paper being transported. An electric field weaker than the predetermined transfer electric field is applied to the leading edge. Even in the presence of a projection generated when the printing paper is cut, the printing paper naturally strips off from the surface of the photoreceptor.Type: GrantFiled: October 19, 2007Date of Patent: April 26, 2011Assignee: Sharp Kabushiki KaishaInventors: Hirokazu Yamauchi, Toshiki Takiguchi, Hiroyuki Murai, Kazuhiro Matsuyama, Masato Kuze

Patent number: 7660547Abstract: A charging device includes a long electrode, a cleaning member, a timing device, a drive source, a load measuring device, and a control device. The drive source moves the cleaning member in the outward direction for a first time period after the outward passage time and then reverses the cleaning member in the homeward position. The load measuring device measures driving load imposed on the drive source while the cleaning member is being moved. The control device controls motion of the drive source to turn the cleaning member from the outward direction to the homeward direction at a predetermined objective point near the second end, based on sum of driving loads imposed on the drive source while the cleaning member is being moved from the first point to a second point located along the outward direction.Type: GrantFiled: July 9, 2007Date of Patent: February 9, 2010Assignee: Sharp Kabushiki KaishaInventors: Toshiki Takiguchi, Masato Kuze, Yuji Kumagai, Hirokazu Yamauchi, Hiroyuki Murai
