<p>In an electrostatographic copying apparatus in which the imaging material is transferred to the copy member by electrical transfer means which leave electrostatic charges on the copy member resisting stripping of the copy member from the original image support surface, and in which a detacking corona generator is provided to partially neutralize those charges before the stripping of the lead edge of the copy member, there is provided an automatic switching system to apply a non-uniform increased transfer charge to the lead edge area of each copy member in comparison to the body of the copy prior to the detacking to improve the effective image transfer to the lead edge area of the copy after stripping. This is preferably provided by a transient over-shoot in the output voltage of a constant current power supply for the transfer means for the lead edge.</p> |
