ABSTRACT:
A method for manufacturing an image displaying medium is provided in that a display element in the form of powder can be filled between facing substrates. After patterning spacer particles on a first flat substrate supplied from a first film roller set on a first roller shaft by a first electrostatic coating device, they are fixed by a first fixing device to form a spacer on the first flat substrate, and then black particles are coated, on the entire surface by a second electrostatic coating device. After coating white particles thereon by a third electrostatic coating device, the black particles and the white particles on the upper part of the spacer are removed by a blade, and a second flat substrate supplied from a second film roller set on a second roller shaft is superimposed, followed by fixing the upper part of the spacer and the second flat substrate by a second fixing device.
