ABSTRACT:
An image formation apparatus including at least a moving body to be charged, a charging device for charging the body to be charged using discharge caused by applying a voltage to a charging member provided in contact with or proximity to the body to be charged, a latent image formation device for forming a latent image on a surface of the body to be charged which is charged by the charging device, and a development device for depositing toner on an image portion of the latent image formed by the latent image formation device, wherein an elastic displacement ratio τe for the surface of the body to be charged is equal to or greater than 40% which is defined by the following formula,in-line-formulae description="In-line Formulae" end="lead"?elastic displacement ratio τe (%)=[(maximum displacement)-(plastic displacement)]/(maximum displacement)×100,in-line-formulae description="In-line Formulae" end="tail"?and the image formation apparatus further includes a protective material feeding device for depositing a protective material on at least a discharge area of the surface of the body to be charged.
