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 2):
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; an input portion configured to input a kind 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 the kind of the transfer material inputted by said input portion, 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 kinds of the transfer materials are all coated paper, and is a second execution time length in a case of a second continuous job in which the kinds of the transfer materials are all plain paper, wherein the second execution time length is longer than the first execution time length.
