Abstract:
An image forming apparatus includes an image transfer belt; a first transfer member; a second transfer member opposed to the first transfer member with the belt therebetween to; an applying device for applying a voltage at least one of the first and second transfer members; and a controller for controlling the applying device to apply to the at least one transfer member a voltage having the same polarity as a regular polarity of toner and a voltage of the opposite a first transfer member cleaning operation. The controller changes a number of image formations to be carried out from a cleaning operation to a next cleaning operation depending on the kind of the sheet. The number controlled by the controller is different depending on the kind of the sheets in a continuous printing job.

Claim (Index 5):
An image forming apparatus comprising:\n a belt configured to a toner image; a first transfer member contacting an outer peripheral surface of said belt and configured to transfer the toner image from said belt onto a transfer material; a second transfer member opposed to said first transfer member with said belt therebetween to form a transfer portion in cooperation with said first transfer member; an applying device configured to apply a voltage at least one of said first and second transfer members; a smoothness sensor configured to detect a smoothness of the transfer material onto which the image is to be transferred; and a controller configured to control said applying device to apply to said at least one transfer member a voltage having a polarity same as a regular charge polarity of toner and a voltage having a polarity opposite to the regular charge polarity for respective predetermined periods to perform a cleaning operation for removing the toner deposited on said first transfer member, in a duration after a transfer material passes through said transfer portion and before a next transfer material reaches the transfer portion, in a continuous job for transferring images onto transfer materials continuously; wherein said controller is capable of changing an execution time length in one duration, on the basis of a detection result of said smoothness sensor, and wherein the execution time length controlled by said controller when the continuous job is carried out under a predetermined ambient condition is a first execution time length in a case of a first continuous job in which the transfer materials are all first transfer materials having a first smoothness, and is a second execution time length in a case of a second continuous job in which the transfer materials are all second transfer materials having a second smoothness, wherein the second execution time length is longer than the first execution time length.
