ELECTROSTATIC IMAGE DEVELOPING TONER AND TWO-COMPONENT ELECTROSTATIC IMAGE DEVELOPER |
| 摘要 |
Provided is an electrostatic image developing toner including a toner mother particle containing a colorant and a binder resin comprising a crystalline resin and an amorphous resin; and an external additive. The external additive includes an inorganic fine particle having a number average major axis in a range of 50 to 100 nm, an average aspect ratio in a range of 3 to 10, and a volume resistivity in a range of 1×1010 to 1×1012 Ω·cm in primary particles. |
