DEVOLOPING DEVICE AND IMAGE FORMING APPARATUS USING THE SAME

摘要

A disclosed developing device comprises a rotatable and flexible continuous belt passing through a fixing nip which is formed by a nip forming member and a backup member; and a first guide disposed inside the belt to guide the belt entering the fixing nip, wherein the first guide includes a first curve unit disposed on the upstream side of the fixing nip to support the belt and a second curve unit disposed on the upstream side of the first curve unit to support the belt. Assuming that the height of the free deformation of the belt with respect to the fixing nip is H and the height of the second curve unit with respect to the fixing nip is h, h is 4 to 10% of H.
