Abstract

Hard image forming apparatuses and methods are described. According to one arrangement, a hard image forming apparatus includes an imaging member comprising a surface, a development system configured to provide a marking agent to the surface of the imaging member to form developed images upon the surface of the imaging member which correspond to latent images formed using the surface of the imaging member, and a transfer system configured to transfer the developed images from the surface of the imaging member to media. The arrangement further includes a contamination removal device configured to remove contamination material from the surface of the imaging member, and a control system configured to control the contamination removal device to contact the surface of the imaging member to remove the contamination material from the surface of the imaging member at a first moment in time and to space the contamination removal device from the surface of the imaging member at a second moment in time where the contamination removal device does not remove the contamination material from the surface of the imaging member.
