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 .tau.e for the surface of the body to be charged is
equal to or greater than 40% which is defined by the following formula,
elastic displacement ratio .tau.e (%)=[(maximum displacement)-(plastic
displacement)]/(maximum displacement).times.100, 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.
