Patent ID: 8103206

Claim:
An electrostatic image forming apparatus, comprising: a charge receptor, movable in a process direction, defining a main surface; a toner application device for applying toner to the charge receptor, and configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor; a primary cleaning device for cleaning the main surface of the charge receptor, the primary cleaning device including at least one biased member having an effective area associated with the main surface relative to motion of the charge receptor; and a secondary cleaning device configured to engage the main surface of the charge receptor downstream of the biased member, wherein the position of the lubrication stripe is controlled to fall within only one of three exclusive timing regions with respect to a position on the main surface of the charge receptor corresponding to a paper trail edge, and the only one of the three exclusive timing regions is selected based on the presence or absence of at least one of a toner reproduction curve patch or an electrostatic voltmeter patch on the charge receptor.
