Title: Image forming device
Inventor: SATO SHOGO
IPC: G03G9/08
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device constituted so that an excellent image can be formed by suppressing the deterioration of non-magnetic one- component developer (toner, for example) and preventing the non-magnetic one-component developer from being defectively electrified. SOLUTION: This laser printer is constituted so that the toner T being as the non-magnetic one-component developer is triboelectrified and carried to the surface of a photoreceptor drum 23 by rotating a supply roller 28 and a developing roller 27 while bringing them into contact with each other. Then, the roller 28 is the sparse foaming roller having open cells whose number is under 30 pieces per one inch. Thus, since large pressure force does not act on the toner T, the toner T is not deteriorated. Besides, titanium oxide whose average grain size is about 40 nm and silica whose average grain size is about 10 nm are mixed and added to the toner T as additive but conductivity is imparted to the titanium oxide being as the large additive by conductive surface processing. Thus, the triboelectrification of the toner T is hardly obstructed by this additive.
