The invention relates to a liquid developer, a process cartridge, an image forming apparatus, and an image forming method. The present invention provides a liquid developer with excellent bending resistance which can prevent toner from falling off from a bent part when a recording medium with an image formed thereon is bent. The liquid developer includes an insulating carrier liquid and toner particles containing a binder resin, the binder resin including a styrene-based thermoplastic elastomer and a styrene thermoplastic resin, and the toner particles being dispersed in the insulating carrier liquid.
