摘要： A sheet feeding device incorporable in an image forming apparatus includes a sheet holder to hold multiple sheets including an uppermost sheet placed on the sheet holder, a sheet separating and feeding unit disposed above the sheet holder and movable between a first position and a second position, a controller to control operations performed by the sheet separating and feeding unit moving between the first position and the second position, and a sheet regulator disposed downstream from the sheet holder in the sheet feeding direction to regulate movement of the multiple sheets on the sheet holder in the sheet feeding direction. The controller controls the separating and feeding unit to move the uppermost sheet forward to abut against the sheet regulator and backward to its original position on the sheet holder to separate the uppermost sheet from the multiple sheets on the sheet holder.

摘要： An image forming apparatus includes an image forming device to form an image on a sheet and a sheet feeding unit to feed the sheet to the image forming device. The sheet feeding unit includes an endless, dielectric belt disposed facing an upper surface of a sheet stack to contact and attract an uppermost sheet to the surface thereof and feed the sheet in the sheet feeding direction, and an electric potential pattern forming unit to form an electric potential pattern on the surface of the dielectric belt. The electric potential pattern has multiple potential holding sections of identical absolute values and opposite polarities disposed adjacent to each other at a uniform pitch. The electric potential pattern forming unit forms the electric potential pattern to have equal numbers of positive potential holding sections and negative potential holding sections.
