    • A developing apparatus provided with a developer holding container (16a) which holds a mono-component developer and an electroconductive elastic development roller (16b ) which is provided inside the developer holding container in a manner enabling it to be driven to rotate. The electroconductive elastic development roller is disposed so that a portion of it is exposed from the developer holding container and contacts the image carrier. The mono-component developer is made to deposit on its rotating surface and form a mono-component developer layer. By the rotation of this, the developer is transferred to the region of contact with the image carrier. The developing apparatus includes an electroconductive leaf spring member (16c) for regulating the thickness of the mono-component developer layer of the electroconductive elastic development roller. This electroconductive leaf spring member is supported integrally at one end by a rotatable rigid support member (16d) and is made to elastically press against and contact the electroconductive elastic development roller for regulating the thickness of the mono-component developer layer of the electroconductive elastic development roller at the other end. The center of rotation of the rigid support member is substantially positioned on the tangent of the electroconductive leaf spring member and the electroconductive elastic development roller.

    • An electrophotographic multi-layered photosensitive member having a top layer of hydrogenated amorphous silicon carbide and the method for forming the top layer are provided. The hydrogenated amorphous silicon carbide has an atomic ratio of carbon to carbon plus silicon C/(Si+C) ranging from 0.17 to 0.47 and a ratio of the number of hydrogen atoms bonded to a silicon atom per silicon atom, to number of hydrogen atoms bonded to a carbon atom per carbon atom, {(Si--H)/Si}/{(C--H)/C}, ranging from 0.3 to 1.0. The top layer is formed on a photosensitive member of hydrogenated amorphous silicon by employing a glow discharge CVD method. The gaseous mixture composed of disilane (Si.sub.2 H.sub.6) and propane (C.sub.3 H.sub.8) mixed with a mol ratio expressed as C.sub.3 H.sub.8 /(Si.sub.2 H.sub.6 +C.sub.3 H.sub.8) ranging from 0.2 to 0.6 is used. Another gaseous mixture is also used with an improved result. The mixture comprises disilane (Si.sub.2 H.sub.6) gas, propane (C.sub.3 H.sub.8) gas, and hydrogen (H.sub.2) gas, the mixing mol ratio of the propane gas to the disilane gas expressed as C.sub.3 H.sub.8 /(Si.sub.2 H.sub.6 +C.sub.3 H.sub.8) ranging from 02 to 0.7, and the mixing mol ratio of the hydrogen gas to the remaining gas, H.sub.2 /(Si.sub.2 H.sub.6 +C.sub.3 H.sub.8), ranging from 1 to 10.
