Image forming apparatus having a charge member disposed near an image bearing member

An image forming apparatus, comprising:

• an image bearing member that bears a toner image;
• a rotary belt that faces the image bearing member, for transferring the toner image onto a transfer material;
• a drive roller that supplies tension to the rotary belt and rotates the rotary belt;
• a power supply;
• and
• a charge brush on which a charge voltage is charged from the power supply, wherein the charge brush contacts the rotary belt and charges toner on the rotary belt,
• wherein the power supply applies a voltage with a polarity that is the same as a polarity of the charge voltage to the charge brush when the rotary belt starts rotating by the drive roller.

An image forming apparatus, comprising:

• an image bearing member that bears a toner image;
• an intermediate transfer member on which the toner image is transferred as a primary transfer from the image bearing member, the toner image on the intermediate transfer member being transferred onto a recording material as a secondary transfer, the intermediate transfer member being movable;
• a power supply;
• and
• a charge member on which a charge voltage is charged from the power supply, for charging a residual toner remaining on the intermediate transfer member after the secondary transfer,
• wherein the charge member has a shape into which a part of toner is accumulated during the residual toner is charged, and
• wherein during a time period when an area in which the primary transfer is first performed on the intermediate transfer member in an operation of the image forming apparatus passes through a position facing the charge member, the power supply applies a voltage with a polarity that is the same as a polarity of the charge voltage to the charge brush.
