Summary: | To provide a liquid developer having good developability and transferability.SOLUTION: A liquid developer includes carrier liquid and toner particles. The toner particles include toner particles A with an equivalent circle diameter of 0.70 μm or more and 1.50 μm or less in an amount of 30% by volume or more and 70% by volume or less, and include toner particles B with an equivalent circle diameter of 0.20 μm or more and less than 0.60 μm in an amount of 30% by volume or more and 70% by volume or less. The liquid developer includes the toner particles A and the toner particles B in an amount of 80% by volume or more and 100% by volume or less. The toner particles A include toner particles a with a shape factor SF1 of 100 or more and 120 or less and a shape factor SF2 of 100 or more and 120 or less in an amount of 85% by number or more and 100% by number or less. The toner particles B include toner particles b with a shape factor SF1 of 130 or more and 200 or less and a shape factor SF2 of 130 or more and 160 or less in an amount of 30% by number or more and 100% by number or less.SELECTED DRAWING: None
