A rotatable image carrier; transfer means for transferring a toner image formed on the image carrier to a recording medium; and cleaning means for removing toner remaining on the image carrier after the toner image is transferred. And an image forming apparatus having a control unit.
When the toner image formed on the image carrier is not transferred to the recording medium, the control means determines the rotation time of the image carrier from the image carrier stopped state to the start of the next image formation. The rotation time of the image carrier from the stopped state of the image carrier when the toner image formed on the body is transferred to a recording medium to the start of the next image formation is at least one rotation of the image carrier. An image forming apparatus. A rotatable image carrier; transfer means for transferring a toner image formed on the image carrier to a recording medium; and cleaning means for removing toner remaining on the image carrier after the toner image is transferred. And an image forming apparatus having a control unit.
When the toner image formed on the image carrier is not transferred to the recording medium, the control means does not stop the rotation of the image carrier from the start of the rotation of the image carrier for cleaning. An image forming apparatus that continues until the rotation of an image carrier for starting image formation is started. The control means determines the rotation time of the image carrier from the image carrier stopped state to the start of the next image formation, from the image carrier stopped state when the toner image formed on the image carrier is transferred to a recording medium. 3. The image forming apparatus according to claim 2 , wherein the rotation time of the image carrier until the next image formation is started is at least one rotation of the image carrier . Examples cleaning means, the image forming apparatus according to any one of claims 1 to 3 characterized by using a rubber blade. Said image bearing member, an image forming apparatus according to any one of claims 1 to 3, characterized in that an intermediate transfer member. It said image bearing member, an image forming apparatus according to any one of claims 1 to 3, characterized in that a photoreceptor. And if not transferred to the recording medium the toner image formed on the image bearing member, any one of claims 1 to 6, characterized in that when the image formation was interrupted by abnormal operation 1 The image forming apparatus described in the item . The image forming apparatus according to claim 7 , wherein the abnormal operation is a jam of a recording medium. The case where the toner image formed on the image carrier is not transferred to the recording medium is a case where the number of recording media prepared in advance is insufficient with respect to the number of images to be formed. The image forming apparatus according to any one of claims 1 to 6 . The case where the toner image formed on the image carrier is not transferred to a recording medium is a case where a control image for adjusting image quality is formed on the image carrier. The image forming apparatus according to claim 1 . The control means determines the rotation time of the image carrier from the state where the image carrier is stopped to the start of the next image formation in accordance with the temperature inside the image forming apparatus, and the toner image formed on the image carrier as a recording medium. to any one of claims 1 to 10 from the image bearing member stop state, characterized in that to determine whether longer than the rotational period of the image bearing member to the next image formation start upon transfer The image forming apparatus described. According to the continuous use time or the number of times of image formation of the image forming apparatus, the control means determines the rotation time of the image carrier from the image carrier stopped state to the start of the next image formation, and the toner formed on the image carrier. 11. The method according to claim 1, wherein it is determined whether or not the rotation time of the image carrier from the stopped state of the image carrier when the image is transferred to the recording medium to the start of the next image formation is longer . the image forming apparatus according to any one.
