ABSTRACT:
An image forming apparatus includes an image bearing member capable of being rotated, a first charging unit, an electrostatic image forming unit, a developing unit, and a second charging unit. The first charging unit is capable of being rotated in the same direction as a rotational direction of the image bearing member with being in contact with the image bearing member, and is capable of charging the image bearing member and toner on the image bearing member. The electrostatic image forming unit is capable of forming an electrostatic image on the image bearing member charged by the first charging unit. The developing unit is capable of collecting the toner on the image bearing member and visualizing the electrostatic image. The second charging unit is disposed downstream of the first charging unit along the rotational direction of the image bearing member, is capable of being rotated in a direction opposite to the rotational direction of the image bearing member with being in contact with the image bearing member, and is capable of charging the toner on the image bearing member.
