Abstract
A developing device includes a developing container that accommodates toner particles, a developing roller that supplies the toner particles to an image carrier on which an electrostatic latent image is formed, and a stirring and transporting member that transports the toner particles inside the developing container toward the developing roller with stirring by rotating around a shaft axis. The stirring and transporting member includes a shaft portion serving as a rotation center and sheet-shaped first stirring blade and second stirring blade fixed to the shaft portion so as to extend outward in a radius direction from the shaft portion. The first stirring blade transports the toner particles in a first transportation direction. The second stirring blade transports the toner particles in a second transportation direction different from the first transportation direction.
