Abstract
A toner layer regulating member and a developing device using the toner layer regulating member. The toner layer regulating member forms a uniform toner layer on a toner transfer unit, electrically charges a toner by friction, and includes a polyolefin-based elastic rubber member which contacts the outer circumference surface of the toner transfer unit and whose surface is ultraviolet-treated. Thus, a uniform toner layer can be formed on the toner transfer unit and the toner is electrically charged by friction. As a result, a high quality image having no defects can be provided.
