Abstract (en)
A method for Direct Electrostatic Printing (DEP) is provided comprising the steps of : creating a flow of charged toner particles (104) in an electrical field from a magnetic brush (103) to a substrate (109), image wise modulating said flow of charged toner particles by a printhead structure (106) comprising printing apertures (107) and control electrodes (106a), image wise depositing toner particles, from said image wise modulated flow of charged toner particles, on said substrate and fixing said toner particles to said substrate, characterised in that said flow of charged toner particles is created directly from said magnetic brush, carrying carrier particles and toner particles, said carrier particles have a specific volume resistivity between 10<1> OMEGA .cm and 10<9> OMEGA .cm and said carrier particles have a specific density lower than 5 g/cm<3>. <IMAGE>
