PROBLEM TO BE SOLVED: To provide a black toner for developing an electrostatic charge image, which achieves a desired image density even when a toner adhesion amount is relatively low, and can form an image without a void, is excellent in chargeability, charging environment stability and stress resistance. To provide. SOLUTION: A black toner for developing an electrostatic image comprising toner particles containing at least a binder resin and a carbon black having a DBP oil absorption of 70 to 120 ml / 100 g, when the adhesion amount is 3.5 g / m 2 . An electrostatic image developing black toner having an image density (ID) of 1.4 or more and an absolute value of a blow-off charge amount of 40 μC / g or more. [Selection figure] None |
