Abstract:
A toner comprising a toner particle, and strontium titanate, wherein the strontium titanate has a specific number average particle diameter, the strontium titanate has a maximum peak (a) at a diffraction angle (2θ) of 32.00 deg to 32.40 deg in CuKα characteristic X-ray diffraction, the half width of the maximum peak (a) is 0.23 deg to 0.50 deg, an intensity (Ia) of the maximum peak (a) and a maximum peak intensity (Ix) in a range of a diffraction angle (2θ) of 24.00 deg to 28.00 deg satisfy a specific relationship, the content of strontium oxide and titanium oxide in the strontium titanate is at least 98.0% by mass,and a sum total Et of a rotational torque and a vertical load in powder flowability analysis of the toner is 100 mJ to 2000 mJ.

Claim (Index 1):
A toner comprising:\n a toner particle; and strontium titanate, wherein a number average particle diameter of primary particles of the strontium titanate is at least 10 nm and not more than 95 nm; the strontium titanate has a maximum peak (a) at a diffraction angle (2\u03b8) of at least 32.00 deg and not more than 32.40 deg in CuK\u03b1 characteristic X-ray diffraction; a half width of the maximum peak (a) is at least 0.23 deg and not more than 0.50 deg; an intensity (Ia) of the maximum peak (a) and a maximum peak intensity (Ix) in a range of a diffraction angle (2\u03b8) of at least 24.00 deg and not more than 28.00 deg in CuK\u03b1 characteristic X-ray diffraction satisfy the following Formula (1):\n ( Ix )/( Ia )\u22640.010 \u2003\u2003(1); \n the strontium titanate is such that, when all elements detected by X-ray fluorescence analysis of the strontium titanate are considered to be in the form of oxides and when a total amount of all the oxides is taken as 100% by mass, a total content of strontium oxide and titanium oxide is at least 98.0% by mass; and a sum total Et of a rotational torque and a vertical load, which is obtained when, in powder flowability analysis of the toner, a propeller-type blade is vertically introduced into a powder layer of the toner in a measurement container while being rotated at a periphery speed of the outermost edge portion thereof at 100 mm/sec, measurement is started from a position of 100 mm from a bottom surface of the powder layer, and the propeller-type blade is introduced to a position of 10 mm from the bottom surface, is at least 100 mJ and not more than 2000 mJ.
