TRANSFERRED MATERIAL FOR IMAGE FORMING DEVICE

摘要

PURPOSE:To conduct excellent printing without a fog and a rear face stain of a paper sheet by specifying charge quantity relationship between a filler and a developer. CONSTITUTION:A transferred material is used for an image forming device which is provided with: an electrostatic latent image forming means for forming an electrostatic latent image in an image carrier; a developing means for feeding a developer to the electrostatic latent image to visualize the electrostatic latent image; a transferring means for transferring a developer image formed in the image carrier to a transferred material; and a mechanism for recovering a developer remaining on the image carrier after transferring to return it to the developing means. In this transferred material, charge quantity Qp of a filler included therein and charge quantity Qt of the developer satisfy a formula I or II. It is disirable that Mohs' hardness of a first filler is 2 or less while that of a second filler is 2 to 7. Also, it is desirable that a filler whose charge polarity is reverse to that of the developer and a filler whose hardness is low for improving productivity of the transferred material are used under a specified mixing ratio to each other.
