Patent ID: 8652735

Claim:
A carrier for developing electrostatic latent image, comprising: a magnetic core particle being a ferrite particle including strontium in an amount of 0.005 to 3% by mass, the amount being measured by fluorescent X-ray spectroscopy; and a resin layer covering a surface of the magnetic core particle, the resin layer comprising a resin obtained by heating a copolymer comprising a unit A having the following formula (A) and a unit B having the following formula (B): wherein R 1 represents a hydrogen atom or a methyl group, each of multiple R 2 independently represents an alkyl group having 1 to 4 carbon atoms, R 3 represents an alkyl group having 1 to 8 carbon atoms or an alkoxy group having 1 to 4 carbon atoms, m represents an integer of 1 to 8, X represents a molar ratio (%) between 10 to 90, and Y represents a molar ratio (%) between 90 to 10.
