Patent number: 8326195Abstract: A transfer device and an image forming apparatus capable of forming an image of smooth image quality with little uneven density, are provided. An alternating voltage is applied so that a first period in which a first peak-to-peak voltage Vpp(1) is applied and a second period in which a second peak-to-peak voltage Vpp(2), lower than the first peak-to-peak voltage, is applied are alternately repeated. In the alternating voltage to be applied, a transfer side potential to shift a toner from an intermediate transfer belt to recording paper sheet and an opposite transfer side potential to shift the toner from the recording paper sheet to the intermediate transfer belt are applied so as to alternate with each other. When f1 denotes a frequency of the first period and f2 denotes a frequency of the second period, f1=f2 is satisfied.Type: GrantFiled: May 27, 2010Date of Patent: December 4, 2012Assignee: Sharp Kabushiki KaishaInventors: Toyoka Aimoto, Toshimasa Hamada

Patent number: 8032062Abstract: A developing unit is configured to develop an electrostatic latent image born on an image bearing member with a developer that has been charged by mixing and agitating toner and magnetic carrier. The developing unit comprises a developing hopper; a developer bearing member; and at least a pair of agitating and conveying members rotationally driven in the developing hopper. The agitating and conveying members are arranged substantially parallel to the developer bearing member and each rotational shaft of the agitating and conveying members is embedded with a magnetic source element whose magnetic poles are laid out so as to produce a magnetic field radially oriented in a particular fixed direction with respect to the agitating and conveying member.Type: GrantFiled: March 19, 2008Date of Patent: October 4, 2011Assignee: Sharp Kabushiki KaishaInventor: Toyoka Aimoto

Patent number: 7904009Abstract: The development device of this invention includes a developer bearing member, a magnet, and a developer regulation member. The magnet is fixedly disposed within the interior of the developer bearing member. The developer regulation member includes at least a magnetic member. And the thickness of this magnetic member along the rotational direction of the developer bearing member is between 0.2 mm and 0.4 mm inclusive. Moreover, if the distance over the developer bearing member, from the position thereupon which the center of the magnetic member along the rotational direction opposes, to the position thereupon at which the magnetism of that magnetic pole which is disposed closest to that position is a maximum, is termed L (mm), and the diameter of the developer bearing member is termed D (mm), then the magnetic member is disposed within the range in which the relationship 0?L/D?0.044 holds.Type: GrantFiled: March 19, 2008Date of Patent: March 8, 2011Assignee: Sharp Kabushiki KaishaInventors: Nobuhiro Maezawa, Toyoka Aimoto, Tomohiro Maeda
