Patent ID: 7217485

Claim:
A toner for electrophotography comprising: a binder resin; a charge control agent; and a colorant, wherein the colorant is a black iron oxide compound containing from 10% by weight to 45% by weight of titanium component calculated in terms of Ti atom in relation to Fe atom when measured by wavelength dispersive X-ray fluorescence spectrometry, and wherein peaks at Bragg angle 2θ of the toner to CuKα X-ray are peak A at 32.9 degrees ±0.3 degrees and peak B at 35.5 degrees ±0.3 degrees, and the intensity ratio of the CuKα X-ray between peaks A and B (A/B) is in the range of 0.3 to 2.0 at a scan speed of 0.5 degrees/min to 4 degrees/min.
