摘要： A developing apparatus includes a developing roller having a surface on which a layer of a non-magnetic single component developing agent (toner) is adapted to be formed, a toner supply roller held in contact with the developing roller so as to electrify the toner and also to supply the toner to the developing roller, and a toner regulating blade for regulating the toner on the developing roller so as to form a film of the toner thereon. The toner regulating blade is formed into a generally L-shape, and with a simple construction, the thickness of the toner layer, formed on the developing roller, can be stabilized, and also a torque of the developing roller can be reduced, and the degradation of a printed image is suppressed, thereby stabilizing the printed image.

摘要： A developing apparatus has a toner reservoir for holding a non-magnetic toner, a toner supply roller including a supply surface for receiving the toner from the toner reservoir and electrifying the toner thereon, an electrostatic latent image carrier including a curved or flat latent image surface on which a latent image formed by an electrostatic voltage distribution thereon is developed by the toner transferred from the supply surface, and a toner seal surface arranged adjacent to the toner supply roller to contact a remaining part of the toner on the supply surface after the latent image development so that the remaining part of the toner is taken into the toner reservoir. The respective frictional coefficients between the toner seal surface and the toner and between the toner particles are selected to prevent a disturbance of toner condition between the toner and the toner seal surface.

摘要： A developing unit, an image-transfer unit and a fixing unit are located in that order in a vertically long housing from the bottom to the top of the housing, and a ventilation passage different from a sheet conveying passage, is formed having an inlet opening formed in the bottom part of the housing and the outlet opening formed in the top part of the housing and extending by way of the developing unit, the image-transfer unit and the fixing unit. Air in the ventilation passage is warmed up by extra heat from the fixing unit so as to induce an ascending air stream which expels NOx and ozone generated by corona discharge and which cools the fixing unit. With this arrangement, the necessity of a ventilating fan can be eliminated so as to miniaturize the electrophotographic printing apparatus and to reduce the cost while eliminating noise caused by a ventilating fan.
