image forming device

Abstract

Abstract PURPOSE:To cover a sleeve with the toner in a developing device when the upper part of an electrophotographic device is opened, by providing a hinge of the rotation center, around which the electrophotographic device which can be divided to upper and lower parts is rotated to be divided into two, near a passage of transfer papers in the downstream side of a photosensitive drum. CONSTITUTION:When the upper part is opened with a hinge 17 as the rotation center, a toner T in a developing device 5 is deflected toward a sleeve 5a, and therefore, the toner T can be used to the last; and a waste toner T' in a cleaner 14 goes far from a photosensitive drum 3, and therefore, troubles on image are difficult to generate, and the capacity of the waste toner T' in a cleaner box 14c is increased. Consequently, the white omission phenomenon of a copied image is not generated even if the remainder of the toner T in the developing device 5 is reduced, and it is difficult that cleaning is defective and the waste toner T' is melt-fixed onto the photosensitive drum 3.
