The present invention provides annelectrophotographic apparatus which has anphotosensitive body, electrostatic image forming devicenfor forming an electrostatic image on thenphotosensitive body, the electrostatic image formingndevice including exposing device for exposing thenphotosensitive body by a digital light in accordancenwith image information, and the exposing devicenexposing a portion that is a background for an image,nand developing device for developing the electrostaticnimage using a developer, wherein rate throughout thendeveloper of the contained particles having a diameternequal to or smaller than 1 µm is 5 to 40 number%,nwherein, when A denotes a one-pixel width and Wvndenotes a width at a half value of a peak in annpotential distribution of the electrostatic imagenformed by exposing the photosensitive drum using thendigital light of one pixel, 0.6 ≤ Wv/A ≤ 1.0 isnsatisfied. |
