Filed: 2002-05-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image forming device capable of always obtaining a stable image even when a low-temperature fixing toner is used by setting a development gap Gp somewhat wide to some extent.  <P>SOLUTION: In a development area wherein a developing sleeve 109 and a photosensitive body 101 face each other, the development gap Gp which is the interval between the both is always set to ≥0.35[mm]. When Gp is ≥0.35[mm], the electric field effect that a toner is attracted toward the developing sleeve is suppressed to some extent. When Gp is too wide, on the other hand, the electric field effect of a developing electric field becomes too weak and it becomes harder to transfer the toner to an image part. Therefore, Gp is not too wide, but ≤2.0[mm] so that no development defect is caused.  <P>COPYRIGHT: (C)2004,JPO
