The disclosure provides an electrophotographic toner and methods for preparing the electrographic toner. The electrographic toner includes a binder, a colorant and a releasing agent, wherein the electrophotographic toner includes strontium (Sr), iron (Fe), titanium (Ti), and silicon (Si) containing particles; wherein, if [Sr], [Fe], [Ti] and [Si] denote the intensities of Sr, Fe, Ti, and Si in the electrophotographic toner, respectively, as measured by X-ray fluorescence spectrometry, then the [Sr]/[Fe] ratio is in the range of about 5.0×10 −1 to about 4.5, the [Ti]/[Fe] ratio is in the range of about 5.0×10 −1 to about 8.1×10 −1 , and the [Si]/[Fe] ratio is in the range of about 2.0×10 −3 to about 4.0×10 −3 . |
