Toner composition having improved charge characteristics and additive attachment

A toner composition comprising blended toner particles comprising:

• base-treated raw toner particles;
• and
• at least one surface additive attached to a surface of the base-treated raw toner particles;
• wherein a ratio of a triboelectric charge of the blended toner composition to a triboelectric charge of the base-treated raw toner particles is from about 0.8 to about 1.2.

A toner composition comprising blended toner particles comprising:

• base-treated raw toner particles;
• and
• at least one surface additive attached to a surface of the base-treated raw toner particles;
• wherein:
• a degree of attachment between the base-treated raw toner particles and the at least one surface additive is from about 10% to about 40%;
• a BET specific surface area of the base-treated raw toner particles is greater than about 1.5 m2/g;
• a ratio of a triboelectric charge of the blended toner particles to a triboelectric charge of the base-treated raw toner particles is from about 0.8 to about 1.2;
• the triboelectric charge of the base-treated raw particles is from about 26 μC/g to about 58 μC/g;
• and
• the triboelectric charge of the blended toner particles is from about 32 μC/g to about 48 μC/g.
