Abstract
A developing device includes a rotatable liquid developer carrying member, a developer container, an electrode opposed to the developer carrying member with a predetermined gap therebetween to form an electric field, and an urging roller provided downstream of the electrode and upstream of a developing position to urge the developer carrying member. An amount of toner on the developer carrying member per unit area in a region downstream of the urging roller and upstream of the developing position with respect to the rotational moving direction is not less than 50% of an amount of the toner on the developer carrying member per unit area in a region interposed between the electrode and the developer carrying member.
