TRANSFERRING AND CARRYING DEVICE

摘要

PURPOSE:To obtain the characteristics to powerfully separate and carry a transfer material by effectively utilizing the electrostatic charge characteristics of a carrying belt without using special means for an electrostatic charger. CONSTITUTION:The carrying belt 9 is constituted of the surface layer constituted of a conductor having 10<11>-10<13>OMEGA.cm volume resistivity and 10-40mum thickness and the base layer constituted of a conductor having the volume resistivity of <=1/10 the volume resistivity of the surface layer and >=10<10>OMEGA.cm volume resistivity. Current is passed from a corona charger 12 provided on the upper stream side of the transfer part where a transfer means 5 exists to the transfer material 8 and a conductive contact means 14 through the carrying belt 9 to previously and sufficiently impart electric charge to the transfer material 8 and the belt 9 so that said material and belt are brought into tight contact with each toner; thereafter, the transfer material 8 is carried to the transfer part. The electrostatic adhesion of a toner image holding body 1 and the transfer material 8 is, therefore, maintained always large by the electrostatic adhesion of the belt 9 and the transfer material 8. The separability of the transfer material 8 from the toner image holding body 1 is thereby enhanced in reliability and the carrying characteristic of the transfer material is stabilized.
