Abstract

PURPOSE:To prevent water droplet from being generated on a cleaning blade and to prevent a photosensitive body from being brought into contact with the water droplet by reducing the contact angle for water of the cleaning blade on which a surface active agent is applied. CONSTITUTION:The cleaning blade 19 to be brought into contact with the photosensitive body 1 is formed in such a way that the contact angle for the water is set at a small angle <=50 deg., and also the surface active agent of non-drip agent is applied on a plane confronting with the photosensitive body 1. In such a way, even when the water is attached on the blade 19 under environment to generate dewing, the water is diffused on the surface of the blade 19, which makes no droplet, and also, diffused water can be evaporated easily. Therefore, it is possible to prevent the water droplet from being generated on the cleaning blade, and also, to prevent the photosensitive body from being brought into contact with the water droplet, and to suppress an adverse effect given on the electrification characteristic and the developing characteristic of the photosensitive body.
