Abstract:
Provided is toner that contains a toner particle, and an external additive containing a strontium titanate particle, wherein the toner has an average circularity of at least 0.935 and not more than 0.995, the strontium titanate particle has a number-average primary particle diameter of at least 10 nm and not more than 60 nm, the strontium titanate particle has a peak in the range of 39.700°±0.150° and a peak in the range of 46.200°±0.150° in a CuKα x-ray diffraction spectrum obtained in the 2θ range of at least 10° and not more than 90° where θ is the Bragg angle, and the ratio of the area Sb of the peak at 46.200°±0.150° to the area Sa of the peak at 39.700°±0.150° is at least 1.80 and not more than 2.30.

Claim (Index 1):
A toner comprising:\n a toner particle; and an external additive containing a strontium titanate particle, wherein: the toner has an average circularity of at least 0.935 and not more than 0.995, the strontium titanate particle has a number-average primary particle diameter of at least 10 nm and not more than 60 nm, the strontium titanate particle has a peak in the range of 39.700\u00b0\u00b10.150\u00b0 and a peak in the range of 46.200\u00b0\u00b10.150\u00b0 in a CuK\u03b1 x-ray diffraction spectrum obtained in the 2\u03b8 range of at least 10\u00b0 and not more than 90\u00b0 where \u03b8 is the Bragg angle, and where Sa is an area of the peak at 39.700\u00b0\u00b10.150\u00b0 and Sb is an area of the peak at 46.200\u00b0\u00b10.150\u00b0, Sb/Sa is at least 1.80 and not more than 2.30.
