Abstract:
1. An image forming unit comprising: a developer bearing body that bears a developer; a supplying member provided so as to face the developer bearing body, the supplying member rotating to collect the developer from the developer bearing body and supply the developer to the developer bearing body; a developer storage portion that stores the developer to be supplied to the supplying member; and a charge providing member that charges the developer held on the supplying member; wherein, in a rotating direction of the supplying member, the charge providing member is disposed on a downstream side of an opposing portion between the developer bearing body and the supplying member; wherein a first voltage is applied to the supplying member; wherein a non-voltage-application time period is provided after the first voltage is applied to the supplying member, the charge providing member being applied with no voltage during the non-voltage-application time period; wherein a second voltage is started to be applied to the charge providing member when the non-voltage-application time period elapses; and wherein the non-voltage-application time period corresponds to a time period required for the supplying member to rotate at least one turn.
