Abstract:
A carrier for use in electrophotography, comprising carrier cores comprising a binder resin and metal compound particles dispersed therein, and a coating resin for coating the surfaces of the carrier cores, wherein;water adsorption TH2O-H (% by weight) after the carrier has been left in an environment of 30Â° C./80% RH, water adsorption TH2O-L (% by weight) after the carrier has been left in an environment of 23Â° C./5% RH, and particle surface area Sm (cm2/g) of the carrier satisfy the following relationship. 6.00Ã—10âˆ’6&lE;TH2O-H/(100Ã—Sm)&lE;1.50Ã—10âˆ’5, â€ƒand 1.00Ã—10âˆ’6&lE;TH2O-L/(100Ã—Sm)&lE;5.50Ã—10âˆ’6.
