A magnetic polymer particle develops a magnetic latent image. The magnetic polymer particle includes a magnetic component, a polymer, and a colorant. The magnetic component is a magnetic particle containing iron having a number average particle diameter of from about 0.2 mum to about 1.2 mum. The magnetic particle is contained in one magnetic polymer particle in an amount of from 1 to 10 particles. The number average particle diameter of the magnetic polymer particle is from about 2.0 mum to about 7.0 mum.
