Abstract
PURPOSE: To make image reproducibility good, faithfullness high and achieve the longer service life of developer by specifying the thickness and friction coefficient of the end part of a developer removing plate having openings for passage of developer and letting the same make contact with the developer support means under the specific contact pressure in the constitution of said plate.
CONSTITUTION: If removing action by a developer removing plate 6 is done, the developer coheres and fuses at the end portion of the removing plate and sometimes produce lumps. Because of this, it is made into an elastic material blade whose end part has a thickness of 0.5mm or less and which contains metal of friction coefficient 0.7 or less and is made of the length of the elastic portion into 1mm or more and further in order to provide a cleaning effect, it is so arranged as to make contact with the developer support means under pressure contact force of 20kg/cm or more. As a result of this, the thin layer of the developer is not formed on the surface of the developer support means despite the long-term development action and the always good development performance may be maintained.
