Abstract
An electrostatic latent image developing carrier includes carrier particles each including a carrier core and first and second coat layers covering a surface of the carrier core. The first and second coat layers give a layered structure in which the first coat layer and the second coat layer are layered in order from the surface of the carrier core. The first coat layer contains a fluororesin. The second coat layer contains a silicone resin and a fluorine silane in an amount of at least 1% by mass relative to a mass of the silicone resin. An area Sof a region of a surface region of the first coat layer that is covered with the second coat layer and an area Sof a region thereof that is not covered with the second coat layer satisfy a relationship represented by '0.05≤S/(S+S)≤0.50'.
