The invention provides an apparatus for developing an electrostatic latent image on a photoreceptor with developer. In the apparatus, there are provided a housing having an open end facing the photoreceptor; a developing device including a sleeve, disposed in the housing in the vicinity of the open end, for supplying developer onto the photoreceptor through the open end; feeder, disposed in the housing at a position further from the open end than the sleeve, for feeding developer to the sleeve; a ridge-like protrusion, provided on a floor of the housing at a position beneath the sleeve, for preventing developer fed by the feeder from passing through between the sleeve and the floor.
摘要:
An automotive body delivered in a direction, and covers such as an engine hood and a trunk lid and doors of the automotive body are opened and held in an open position. Thereafter, prescribed areas of the automotive body are coated, and those doors which are located downstream with respect to the direction in which the automotive body is delivered and those areas of the automotive body which correspond to those doors which are located upstream with respect to the same direction, are coated. Thereafter, the covers and the doors of the automotive body are closed.
