摘要： A printing device for reproducing information, comprising a movable image-forming element (10) having a dielectric surface, an image-forming station (11) in which a magnetic roller (84) is disposed with a rotatable electrically conductive sleeve (92), first means to generate an electric field between the image-forming element (10)and the magnetic roller (84) in accordance with an information pattern, while an electrically conductive magnetically attractable toner powder is present in the image-forming zone (90), and second means consisting of a magnetic system (85) which generate a magnetic field in the image-forming zone (90). A force is applied to the sleeve (92) to press the latter, at the image-forming zone (90), against spacer means disposed inside the sleeve (92) or against the magnetic system (85).
As a result, a well-defined space is created in the image-forming zone (90) between the sleeve (92) and the image-forming element (10) so that no distortion of the toner brush occurs in the image-forming zone (90).

摘要： A cylindrical structure is formed by a cylinder and a terminal engaging member, such as a gear or flange for rotating the cylinder, fastened to at least one end of the cylinder. The terminal engaging member has a head inserted into the cylinder and a recess adjacent to the head and is fastened to the at least one end of the cylinder by bending and cutting an end brim of the associated cylinder end into the recess of the terminal engaging member. The cylindrical structure is characterized by the joint between the cylinder and the terminal engaging member, which joint can be formed securely in a simple manner. The cylindrical structure may be embodied, e.g., as a photosensitive drum or a developing sleeve for electrophotography.

摘要： A developing apparatus having a developing sleeve (10b) for carrying developer to a developing station. The developing sleeve (10b) contains therein a magnet (10a). A magnetic member (21) is disposed closely to the developing sleeve (10b), extending along a circumference of the sleeve (10b). The magnetic member (21) cooperates with said magnet (10a) to form a magnetic brush in a gap between the sleeve (10b) and the magnetic member (21) itself. The magnetic brush is effective to prevent possible leakage of the developer to the outside of a developer container (8) at longitudinal ends of the sleeve (10b).

摘要： The developing device of an electrical photocopying apparatus comprises a developing drum (37). This drum is made of a hollow non-magnetic cylinder (29) and of a set of magnets rotatingly mounted inside the hollow cylinder. On the outer conductive surface of hollow cylinder (29) is placed a magnetic brush made of small magnetic particles for development, said particles being transferred from the magnetic brush onto an intermediary image carrier by means of the electrical field from the latent image. The thickness of wall (53) in the part of hollow cylinder (29) adjacent to the intermediary image carrier (1) is reduced, thus allowing a larger scanning surface in order to achieve a uniform production of the development image.
