Abstract

PURPOSE: To prevent the splashing of a toner by installing a small electrode for preventing splashing of a developer near the downstream side of a developer flying region between a latent image carrying member and a developer carrying member.
CONSTITUTION: The wire electrode 37 is extended near the downstream side of the developer flying region 36 between a photosensitive drum 11 and a developing sleeve 32. The prescribed bias voltage of the same polarity as the charge polarity of the developer 31 is impressed by a power source 38 to this wire electrode 37. The developer 31 which tends to splash from the developer flying region 36 between the photosensitive drum 11 and the developing sleeve 32 is, therefore, repulsed by the electric field generated by the wire electrode 37 and is returned to the developing sleeve 32 side, by which the developer 31 is recovered into a developing device 25 as the developing sleeve 32 rotates.
