摘要： An image-forming method includes forming an electrostatic image on an electrostatic image bearing member which has been charged; developing the electrostatic image to form a toner image; transferring the toner image on the electrostatic image bearing member with or without mediating an intermediate transferring member onto a transfer material; and fixing the toner image on the transfer material. The electrostatic image bearing member is a photosensitive member obtained by sequentially laminating a photoconductive layer and a surface layer formed of hydrogenated amorphous silicon carbide, and a sum of an atomic density of silicon atoms and an atomic density of carbon atoms in the surface layer of the photosensitive member is 6.60×1022 atoms/cm3 or more. The toner has a binder resin and magnetic iron oxide particles, and the magnetic iron oxide particles contain Fe(2+) at a content of 20.0 mass % or more and 25.0 mass % or less.

At that time, equation II applies, where the thickness of the interlayer is (a), the wavelength of incident light is lambda, and m is an integer of >=0, the material and the thickness are selected so as to satisfy said equation, thus permitting the reflection of both interfaces to be weakened, and stable spectral sensitivity to be obtained.

摘要： PURPOSE:To obtain a electrophotographic sensitive body low in residual potential and superior in durability or the like without considering a combination between an electrostatic charge transfer material and a binder by incorporating a specified metal compd. in a charge transfer layer and forming a laminate type photosensitive layer composed of the charge transfer layer and a charge generating layer. CONSTITUTION:The charge transfer layer contg. at least one kind of oxide or chloride of a metal, such as Fe, Ni, Cu, Cr, Sn, In, Ag, or the like together with a charge transfer layer is formed in combination with the charge generating layer on a conductive substrate. The charge generating layer is formed on the conductive substrate by vapor depositing the charge generating material, such as Se, Se alloy, amorphous Si, or org. pigment, or incorporating it in the binder and coating the substrate with the binder contg. it. The charge transfer layer is formed on the charge generating layer. The addition of the metal compd. makes it unnecessary to consider the conventional problems that the residual potential depends on the combination between the charge transfer material and the binder, and repeating the use increases residual potential, thus permitting the photosensitive body to be extended in life.

A photoconductive layer 3 made of Se or contg. Se as a main component, and also Te or As is formed on the layer 2, and then, an insulating layer 4 of a polyester film or the like is formed on the layer 3. When the layer 3 is substituted for a 2-layer type photoconductive layer 3' consisting of a charge transfer layer 3b of Se type doped with ≤4,000ppm halogen, and a charge generating layer 3a contg. 5W 25% Te, the composite layer 3' is made larger in spectral sensitivity region than the single Se layer 3, and enhanced in efficiency. When the layers 3, 3' are formed, it is preferable to heat temp. of the substrate to 55W65°C to carry out vapor deposition, and it is more desirable to heat treat it to 30W65°C after forming the layer 4. As a result, the Te layer 2 is enhanced in charge injection performance at the time of primary charging, and since it has blocking ability at the time of secondary charging, high contrast is obtained.
