Carrier particles for electrophotography, two-component developer and the image-forming method

摘要

A carrier for use in electrophotography has carrier cores comprising a binder resin and metal compound particles dispersed therein, and a coating resin for coating the surfaces of the carrier cores. Water adsorption TH2O-H (% by weight) after the carrier has been left in an environment of 30°C/80%RH, water adsorption TH2O-L (% by weight) after the carrier has been left in an environment of 23°C/5%RH, and particle surface area Sm (cm2/g) of the carrier satisfy the following relationship:6.00 × 10-6 ≤ TH2O-H/(100 × Sm) ≤ 1.50 × 10-5, and1.00 × 10-6 ≤ TH2O-L/(100 × Sm) ≤ 5.50 × 10-6.
