Abstract: An electrostatic image developer includes a toner containing an external additive having a volume-average particle size of about 80 to 400 nm and an average circularity of about 0.7 to 0.85. The developer is used in an image forming apparatus including an image-carrying member having a top surface layer containing fluorocarbon resin particles, and a developer-carrying member that faces the image-carrying member and carries an electrostatic image developer, in which a value obtained by dividing the amount of developer on the developer-carrying member [g/m2] by a shortest distance between the image-carrying member and the developer-carrying member [?m] is about 0.8 to 1.8, and a peripheral velocity ratio of the developer-carrying member to the image-carrying member is about 1.5 to 5.0 or the developer-carrying member moves in a direction opposite to the image-carrying member in a facing portion.

Abstract: A developing device includes a first developer holder and a second developer holder. The first developer holder is disposed so as to face an image holding member and rotates so as to move in a direction opposite to a direction of movement of the image holding member at a first facing portion. The second developer holder is disposed downstream from the first developer holder in the direction of movement of the image holding member so as to face the image holding member and rotates so as to move in the same direction as the image holding member moves at a second facing portion. A value obtained by dividing an amount of developer per unit area held on the first developer holder by a shortest distance between the image holding member and the first developer holder is approximately in a range from 1.00×103 kg/m3 to 1.60×103 kg/m3.
