<p>PROBLEM TO BE SOLVED: To make it hard to cause heat fusion on an electrode upon forming an image and obtain the sufficient contrast of density by employing a toner, obtained by adding a ctrosslinking agent into polyester resin. SOLUTION: A toner supplying device 10, employed in an image forming device, is provided with a toner reservoir 21, receiving toner 16 therein, in a toner case 11 while the toner 16 is supplied to a carrying roller 14 through a supplying roller 12, then, the toner 16, carried by the carrying roller 14, is transferred toward an aperture electrode body 1. The aperture electrode body 1 is pressed against the carrying roller 14 at the aperture position of an insulating sheet under a condition that a control electrode 4 is opposed to the side of a supporting body 20. In this case, the toner 16 is formed by adding a crosslinking agent into a binder resin or polyester resin while aromatic polyisocyanate is employed preferably as the crosslinking agent. On the other hand, the toner is prepared by adding 1-5 parts of the crosslinking agent into 100 parts of the resin.</p> |
