PURPOSE:To equip a carrier for electronic photograph according to the invention with excellent durability and anti-toner spent property, lessen variation of the electrostatic charging characteristic despite changing environment, and build a stable image by enwrapping the carrier with polymeride or copolymeride including a specific unitary component. CONSTITUTION:A carrier for electronic photograph according to the invention is enwrapped with polymeride or copolymeride including a unitary component as expressed by Eq. I, where R1, R2 are alkyl radical or aryl radical either identical or different, A is organic anion, poly-acid ion, heteropolyacid ion, or halogen, and n is either of 0, 1, 2, 3. This lessens change in the electrostatic charging amount despite changing environment, provides stable image density, and eliminates deterioration of the carrier for example becoming toner spent in the course of long time service. |
