Abstract:
An image forming method uses a color toner including a yellow toner, a magenta toner, a cyan toner, and a black toner. The image forming method includes a toner image forming step of forming a toner image by developing the color toner on an electrostatic latent image formed by charging and exposing a surface of an electrostatic latent image bearing member, a transfer step of transferring the toner image onto a recording medium to form a color toner image, and a fixing step of fixing the color toner image on the recording medium. Each toner contain at least a binder resin, a coloring agent, a release agent, and a layered silicate compound. The volume average particle diameter of each toner is 4 to 6 μm. The content of the aluminum element in each toner represented by the Net intensity by WDXRF analysis has a specific relationship.

Claim (Index 1):
An image forming method using a color toner including a yellow toner, a magenta toner, a cyan toner, and a black toner, the method comprising:\n a toner image forming step of forming a toner image by developing the color toner on an electrostatic latent image formed by charging and exposing a surface of an electrostatic latent image bearing member; a transfer step of transferring the toner image onto a recording medium to form a color toner image; and a fixing step of fixing the color toner image on the recording medium, wherein the yellow toner, the magenta toner, the cyan toner, and the black toner each contain at least a binder resin, a coloring agent, a release agent, and a layered silicate compound, a volume average particle diameter of the yellow toner, the magenta toner, the cyan toner and the black toner is 4 \u03bcm to 6 \u03bcm, and when Al (Y) kcps is a content of aluminum element in the yellow toner expressed by Net intensity by wavelength dispersion type fluorescent X-ray analysis, Al (M) kcps is a content of aluminum element in the magenta toner expressed by Net intensity by wavelength dispersion type fluorescent X-ray analysis, Al (C) kcps is a content of aluminum element in the cyan toner expressed by Net intensity by wavelength dispersion type fluorescent X-ray analysis, and Al (K) kcps is a content of aluminum element in the black toner expressed by Net intensity by wavelength dispersion type fluorescent X-ray analysis, the following Formulae (1) to (3) are satisfied.\n [Math. 1] \n Al ( Y )< Al ( M )< Al ( C )\u2003\u2003(1) \n Al ( Y )< Al ( K )< Al ( C )\u2003\u2003(2) \n 3.18<[ Al ( C )\u2212 Al ( Y )]<8.65\u2003\u2003(3)
