| 摘要 |
An image forming apparatus, 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 towards an image receiving surface, said image forming apparatus including: a background voltage source for producing a background electric field which enables a transport of charged toner particles from said particle carrier towards said image receiving surface; a printhead structure arranged in said background electric field, including a plurality of apertures and control electrodes arranged in conjunction to the apertures; control voltage sources for supplying control potentials to said control electrodes in accordance with the image information to selectively permit or restrict the transport of charged toner particles from the particle carrier through the apertures; said image receiving surface being arranged for movement in relation to the printhead structure for intercepting the transported charged toner particles in an image configuration and is formed on an intermediate image receiving member which is arranged for transferring deposited toner particles from said image receiving surface to an information carrier.
