Abstract
A liquid developer contains toner particles containing a binder resin and a colorant, a liquid carrier, a toner-particle dispersant, and a compound represented by formula (1). The liquid carrier contains at least one selected from the group consisting of liquid aliphatic hydrocarbons and liquid polysiloxanes. The toner-particle dispersant is an amine-based dispersant.
Claims8
A liquid developer, comprising:
- toner particles containing a binder resin and a colorant;
- a liquid carrier;
- a toner-particle dispersant;
- and
- a compound represented by formula (1),
- the liquid carrier containing at least one compound selected from the group consisting of liquid aliphatic hydrocarbons and liquid polysiloxanes,
- the toner-particle dispersant being an amine-based dispersant:
- where in formula (1), R1 and R2 are each independently an alkyl group having 6 to 20 carbon atoms.
