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 6):
The toner according to  claim 1 , wherein the coverage ratio of the surface of the toner by the strontium titanate particle, as measured with an x-ray photoelectron spectrometer, is at least 5.0 area % and not more than 20.0 area %.
