    摘要： 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, elastic displacement ratio τe (%)=[(maximum displacement)-(plastic displacement)]/(maximum displacement)×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.

    摘要： An image forming apparatus includes a latent image bearer, an intermediate transferor, a primary transferor, a second transferor, and a cleaning blade. The latent image bearer has a surface onto which a lubricant comprising zinc stearate is supplied. The intermediate transferor has a surface onto which the toner image is transferred, the surface including an adhering region to which the lubricant from the latent image bearer adheres. The cleaning blade cleans the surface of the intermediate transferor including the adhering region, after the toner image is secondarily transferred. In a region outside at least a horizontal A4 sheet passing width on the intermediate transferor, a ratio of a peak area derived from zinc stearate to a peak area derived from the intermediate transferor in a difference spectrum between attenuated total reflection (ATR) infrared absorption spectrums of the intermediate transferor in an unused state and after use is 0.892 or less.
