摘要： Provided is an image forming apparatus including a unit for controlling each voltage value of peak-to-peak voltages of DC and AC voltages applied to a charging unit for charging an image bearing member, in which a residual charge eliminating unit conducts charge elimination on a surface of the image bearing member while at least the charging unit undergoes an application of the AC voltage including the peak-to-peak voltage that is, in the case of setting at Vth a discharge start voltage to the image bearing member when applying the DC voltage to the charging unit, twice or smaller than this discharge start voltage Vth. With this image forming apparatus, it is possible to restrain an occurrence of a defect in an image which is attributable to an instability of a charging potential on the image bearing member by stabilizing a potential on the image bearing member at zero even in a case where the AC voltage applied to the charging unit for the image bearing member is the peak-to-peak voltage that is twice or smaller than Vth.

摘要： An image forming apparatus includes a photosensitive drum, a charging roller, a transfer roller, and a toner charging brush, wherein the toner charging brush reciprocates in a longitudinal direction of the photosensitive drum. In the image forming apparatus, when a number of rotations per a unit time of the image bearing member is assumed to be “a” and a number of times of reciprocation per unit time of the toner charging brush is assumed to be “b”, assuming that R=b/a, R is set to be in a range of 1/25≦R≦3. However, R=m/n (m and n are integers of 5 or less) is excluded. Consequently, generation of a periodic attachment pattern appearing on the photosensitive drum is eliminated.

摘要： The image forming apparatus includes an image bearing member; a transfer belt used to transfer a toner image from the image bearing member to a transfer material; a transfer unit adapted to form a transfer nip in conjunction with the image bearing member through the transfer belt; and a control part adapted to control a rotation direction of the transfer belt, wherein in a cleaning mode, the control part rotates the transfer belt in a direction opposite to the rotation direction of the transfer belt during image formation at least by an amount equal to or larger than width of the transfer nip in the rotation direction of the transfer belt. This prevents foreign material from being trapped between the transfer belt such as an intermediate transfer belt or transfer material conveyance belt and a sheet member and thereby reduces density irregularities in a longitudinal direction of the belt.
