Abstract:
1. A cleaning device for removing particulate from a charging device in an electrophotographic device comprising: a flexible, elongated substrate including a pad comprising open-cell foam capable of absorbing and retaining particulate, said pad including a concave engaging surface having a length of 4.0-8.0 mm; said substrate having first and second portions, wherein said substrate comprises a material having a flexural modulus less than or equal to 400,000 psi, and wherein said substrate is capable of being flexed to be positioned between said charging device and a surface in said electrophotographic device; wherein said first and second portions define an angle of less than 180 degrees, and wherein said substrate, as positioned between said charging device and said surface in said electrophotographic device applies a pressure onto said pad when said pad contacts said charging device and said pad configured to engage and apply a cleaning pressure to and absorb and retain particulate from said charging device along said length of said pad concave engaging surface.
