    摘要： A developing device (10) using a one-component developer composed of coloured fine synthetic resin toner particles, which device comprises a vessel (16) for holding the developer, and a developing roller (18) rotatably provided within the vessel (16) in such a manner that a portion of the roller (18) exposed therefrom is resiliently pressed against a surface of an electrostatic latent image formation drum (14). The roller (18) is formed of a conductive porous rubber material (18b) so that pore openings appear over a surface of the roller (18), whereby during rotation of the roller (18), the toner particles are captured and held by the pore openings of the roller (18) to form a developer layer therearound and are carried to the surface of the drum (14). The developing device (10) further comprises a blade (20) or roller member provided within the vessel (16) and which is resiliently engaged with the developing roller (18), the regulating thickness of the developing layer formed around the developing roller (18).
