DIRECT PRINTING APPARATUS AND METHOD

摘要

An image forming apparatus (2000) in which an image information is converted into a pattern of electrostatic fields for modulating a transport of charged toner particles from a particle carrier (2033) towards an image receiving surface, wherein apertures (2052) are arranged transversely to a printing direction (PD) of a printhead structure (2005) with an average pitch (pav), and extend a first distance (Iap) from a particle-receiving plane (A) to a particle-emitting plane (B) of the printhead structure (2005). The particle-receiving plane (A) is at a second distance (Ik) from the charged toner particles (PA) on the particle carrier (2033). The image receiving surface is provided on at least one surface portion of a back electrode member (2012) and can be caused to move at least in the printing direction (PD) in relation to the printhead structure (2005) for intercepting the transported charged toner particles in an image configuration (IM).
