Abstract
An image forming apparatus includes a liquid developer holding member and a bias voltage applying unit. The liquid developer holding member includes a conductive core member and a dielectric layer provided on an outer circumference of the core member, and the dielectric layer includes a dielectric material and has at least one concave portion formed on a surface thereof. The at least one concave portion of the dielectric layer holds therein a liquid developer containing a solid developer dispersed in a carrier liquid.
