Abstract
A charging apparatus for applying a uniform electrostatic charge to a charge retentive surface is provided. There is also provided a housing; an array of pin electrodes supported by said housing and positioned adjacent said surface in a non-contact relationship; wherein each pin in said array being composed of austenitic stainless steel; a power supply operatively coupled to said pin electrodes for supplying a predetermined current to each of said pin electrode, wherein said predetermined current ranges from 5 μA/pin and which co-acts with a protruding distance of the pins from the housing so as to optimize the charge uniformity and to minimize the ozone generated within said charging apparatus.
Claims4
A charging apparatus for applying a uniform electrostatic charge to a charge retentive surface, said apparatus comprising:
- a housing;
- an array of pin electrodes supported by said housing and positioned adjacent said surface in a non-contact relationship;
- said pin array comprises austenitic stainless steel and a power supply operatively coupled to said pin electrodes for supplying a predetermined current to each of said pin electrode, wherein said predetermined current is about 5 μA/pin and which co-acts with a protruding distance of the pins from the housing so as to optimize the charge uniformity and to minimize the ozone generated within said charging apparatus.
