Abstract
An electrophotographic copying process is disclosed comprising the steps of performing a cleaning operation on a recording element by carrying out at least one rinsing operation of the element utilizing a first quantity of a developer liquid; performing a series of copying cycles comprising charging, exposing, developing with a liquid developer, transferring and fixing; and intermittently performing additional cleaning operations independently of each cycle of the series of copying cycles using a quantity of developer liquid which is at most as great as the first quantity.
Claims16
An electrophotographic copying process comprising the steps of:
- performing a cleaning operation on a recording element by carrying out at least one rinsing operation of the element utilizing a first quantity of a developer liquid;
- performing a series of copying cycles comprising charging, exposing, developing with a liquid developer, transferring and fixing;
- and
- after at least one copying cycle, performing additional cleaning operations by rinsing the element with a second quantity of developer liquid which is between "0" and "a" wherein "a" is an amount less than said first quantity and "0" means a completely omitted rinsing of developer liquid;
- the supply of developer liquid for rinsing said element being at least partially interrupted during said series of copying cycles.
An electrophotographic copying apparatus comprising means for performing a cleaning operation on a recording element by carrying out at least one rinsing operation of said element utilizing a first quantity of a developer liquid;
- means for performing a series of copying cycles;
- and means for performing additional cleaning operations after at least one copying cycle by rinsing said element with a second quantity of developer liquid which is between "0" and "a", wherein "a" is an amount less than said first quantity and "0" means a completely omitted rinsing of developer liquid;
- said apparatus further comprising means for at least partially interrupting the supply of liquid developer for rinsing said recording element during part of said series of copying cycles.
