Abstract
An image forming apparatus includes: an intermediary transfer member; an image forming unit; a transfer member; a cleaning member; and a setting portion for setting an absolute value of the first cleaning voltage applied to the cleaning member when a region of the intermediary transfer member, passed through the transfer portion where a higher transfer voltage is applied to the transfer member during passing of the recording material through the transfer portion, passes through the cleaning portion and for setting an absolute value of the second cleaning voltage applied to the cleaning member when a region of the intermediary transfer member, passed through the transfer portion where a lower transfer voltage is applied to the transfer member during passing of the recording material through the transfer portion, passes through the cleaning portion. The absolute value of the second cleaning voltage is higher than that of the first cleaning voltage.
