<p>PROBLEM TO BE SOLVED: To prevent central blanking in transferring and to realize excellent transfer to rough paper. SOLUTION: The toner is used in an image forming device consisting of an intermediate transfer unit where a toner image formed on a photoreceptor 110 is primarily transferred to an intermediate transfer belt 360 by a primary transfer roller 320, and the toner image is secondarily transferred to a recording medium by a secondary transfer roller 380, and also a primary transfer means and a secondary transfer means respectively function as a transfer electrode. Then, the looseness apparent density of the toner is >=0.35 g/cc, and the shape factors SF-1 and SF-2 of the toner are <=150 and <=140, respectively.</p> |
