ABSTRACT:
An image recording apparatus charges toner particles and forms a suspension of the charged toner particles. The image recording apparatus generates an electric field between a control electrode which has apertures and a back electrode, to directly control a flow of the charged toner particles, and to record an image on an image recording medium which passes between both electrodes. The image recording apparatus has an adjusting unit which adjusts the density of the suspension of the charged toner particles. The adjusting unit adjusts the density of the suspension of the charged particles in accordance with a signal output from a manual adjusting member, when a user operates the manual adjusting member. Density of the image on the image recording medium is adjusted on the basis of operation of the adjusting unit. The particles can be supplied by a speed variable ciliary member or a vibrating belt.
