Patent ID: 8923718

Claim:
An image forming apparatus, comprising: an image forming unit configured to form a toner image; a movable image bearing member configured to bear the toner image formed by the image forming unit; a movable conveying belt configured to convey a recording material; a transfer member configured to transfer, in a transfer portion, the toner image from the image bearing member to the recording material which is conveyed by the conveying belt; a power supply configured to apply a voltage to the transfer member; a first blade member disposed downstream of the transfer portion and upstream of the image forming unit in a direction in which the image bearing member moves and configured to be in contact with the image bearing member; a second blade member configured to be in contact with the conveying belt; and an execution unit configured to form a toner band in a non-image area existing between image areas of the image bearing member when toner images are formed continuously, and configured to set a toner band passing voltage so that an absolute value of a first voltage when information about toner usage in an image formation is equal to or greater than a predetermined amount is greater than an absolute value of a second voltage when the formation is smaller than the predetermined amount, wherein the toner band passing voltage is a voltage applied to the transfer member from the power supply when the toner band passes the transfer portion and has the same polarity as that of the voltage applied to the transfer member when the toner image is transferred.
