Title: Image forming device
Inventor: MIZUTANI YOSHIKO
IPC: G03G15/04
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To obtain image quality having excellent color reproducibility without making jitter conspicuous and to obtain a smooth image without making a screen structure conspicuous even on a halftone image by setting the toner scattering (image scattering) amount of a final image to a value equal to or more than a specified value. SOLUTION: As to a transfer electric field; a constant current set valve is about 5 to 20μA in the case of primary transfer by which toner moves to an intermediate transfer body 106 from a photoreceptor 101, the constant current set value is 10 to 30μA in the case of secondary transfer by which the toner moves to a material 113 to be recorded from the body 106, and the image scattering occurs as the constant current set value is large and the image scattering is hard to occur as the constant current set value is small.  The transfer electric field and the fluidity of the toner are combined and the image scattering amount of the final image is set to the value equal to or more than the specified value, that is, >=15μ, so that density fluctuation becomes adequately inconspicuous by the existence of the image scattering and human eye is hard to sense noise occurrence; therefore, the jitter becomes inconspicuous and the good image can be obtained.
