摘要：
A liquid developer for developing an electrostatic latent image having a carrier fluid and electrically charged toner particles dispersed therein, wherein the liquid developer satisfies the following relationship: 25.0.gtoreq.V.sub.0 /.DELTA.V.sub.10 .gtoreq.1.5 wherein V.sub.0 denotes surface potential of a toner particle layer electrically deposited on a conductive substrate by applying bias voltage between the substrate and an electrode confronting with the substrate, and .DELTA.V.sub.10 denotes change of the surface potential decaying for 10 seconds after shutting off the bias voltage.
