ABSTRACT:
A developing device includes a developer bearing body that partially faces the inside of a developer storing chamber, a first developer carrying member disposed in the chamber together with the body, and a second developer carrying member disposed in the chamber together with the first carrying member. The body is rotatable and bears a developer. The first carrying roller rotates to carry the developer in an axial direction, and the second carrying member rotates to carry the developer in an axial direction. The first carrying member carries the developer from end portions of the chamber toward a center portion of the chamber, and the second carrying member carries the developer from the center portion toward the end portions. An amount of the developer carried by the first carrying member is greater than an amount of the developer carried by the second carrying member.
