摘要： An image forming apparatus includes a rotatable image bearing member for bearing a developer image, a developing device for developing an electrostatic latent image on the image bearing member into the developer image and a cleaning blade. In addition, a controller executes a stop operation of the image bearing member in which the image bearing member is, after being temporarily stopped at an end of an image forming operation, rotated in the same direction as that during the image forming operation and then is rotated in a direction opposite to that during the image forming operation, and a predicting portion predicts a remaining usable lifetime of the image bearing member. In the stop operation of the image bearing member after the remaining usable lifetime is below a threshold, the controller controls an amount of rotation in the direction opposite to that during the image forming operation so as to be smaller than the amount of rotation before the remaining usable lifetime is below the threshold.

摘要： An image forming apparatus includes an image bearing member for bearing a developer image; a driving portion for rotationally driving the image bearing member; a developing device for developing an electrostatic latent image on the image bearing member into the developer image; a cleaning blade, slidably contacting the image bearing member which is rotated, for removing from the image bearing member a developer remaining on the image bearing member after transfer of the developer image; a controller capable of executing a stop operation of the image bearing member in which the image bearing member is, after being temporarily stopped at the time of an end of an image forming operation, rotated in the same direction as that during the image forming operation and then is rotated in a direction opposite to that during the image forming operation; and a predicting portion for predicting a remaining usable lifetime of the image bearing member. In the stop operation of the image bearing member after the remaining usable lifetime is below a threshold, the controller controls an amount of rotation in the direction opposite to that during the image forming operation so as to be smaller than the amount of rotation before the remaining usable lifetime is below the threshold.
