流下案内部を設けたことを特徴とする現像装置。 A developer carrying member carries and conveys a developer and develops an electrostatic latent image on a latent image carrier with the carried and conveyed developer; A developer stirring and pumping member that supplies the developer to the carrier member, and a developer regulating member that scrapes off excess developer from the developer carried on the developer carrier member before development and regulates the layer thickness to be suitable for development. Then, the scraped developer is received on the developer flow plate, and the developer is caused to flow obliquely by the guiding action of a plurality of fins protruding from the developer flow plate, and is moved upward in the axial direction of the developer carrying member. a developer rectifying member that causes the collected developer to fall toward the developer stirring and pumping member while moving the developer from one end side to the other end side;
a developer transport screw member that receives the developer on the other end side of the scraped developer and transports the developer from the other end side to the one end side; A developing device comprising a developer flow guide section that causes the developer transported to the end side to fall onto the developer flow plate.
