A developing apparatus faces an image carrier carrying an electrostatic latent image and comprises a developing section for developing the electrostatic latent image by supplying a developing agent thereto and a feeding section for feeding the developing agent to the developing section while stirring. The feeding section has a rotatable shaft member, a blade body formed spirally on an outer peripheral surface of the shaft member for feeding the developing agent in a shaft direction, and a plurality of projections located between tilted blade portions on the outer peripheral surface of the shaft member. The projections, each being placed at an interval from the tilted blade portions of the blade body and are arranged at predetermined intervals along circumference of the shaft member.
