Abstract: A developing apparatus includes a developer bearing member, a developer container configured, and a storage tank arranged within the developer container and configured to store liquid developer to be supplied to the developer bearing member. The storage tank includes a first bottom surface including an inclined portion that is inclined downward with respect to a horizontal direction in a rotational axis direction of the developer bearing member, and a discharge port arranged on a lower end of the inclined portion of the first bottom surface. The developer container includes a second bottom surface including an inclined portion that is inclined downward with respect to the horizontal direction toward an opposite direction as the inclined portion of the first bottom surface in the rotational axis direction of the developer bearing member, and a discharge port arranged on a lower end of the inclined portion of the second bottom surface.

Abstract: An image forming apparatus includes a control unit configured to execute a stop mode in which, after image forming operation is stopped, a developer bearing member is rotated for a predetermined time with a potential difference between a film forming electrode and a developer bearing member set to zero or smaller than that during image formation, and thereafter, the rotation of the developer bearing member is stopped.

Abstract: A developing device includes a developer carrying member (41) rotating while carrying a liquid developer on a carrying surface (41b) and an end portion restricting member (46) for restricting movement of the liquid developer, carried on the carrying surface (41b), to an outside of the carrying surface (41b). A contact angle between the end portion restricting member (46) and the liquid developer is set so as to be larger than a contact angle between the carrying surface (41b) of the developer carrying member (41) and the liquid developer. By this, when the developer carrying member (41) is separated from the end portion restricting member (46), deposition of the liquid developer in a large amount in the neighborhood of an end (41c) of the carrying surface (41b) is prevented.

Abstract: A developer container 53 is capable of supplying a liquid developer to a portion, of a surface of a cleaning roller 58, between a cleaning position X and a contact position Y with respect to a rotational direction of the cleaning roller 58. A free end of a cleaning blade 56 is positioned in a range of 65° or more and less than 95° as a positive angle of the rotational direction of the cleaning roller 58 when a line passing through a center of the cleaning roller 58 and an upper end portion of the cleaning roller 58 with respect to a direction of gravitation is at 0° (reference line G). In this case, the cleaning blade 56 is disposed so that an angle ? between a line F perpendicular to a line E connecting the center of the cleaning roller 58 and the free end of the cleaning blade 56, and the cleaning blade 56 is in a range of 35° or more and less than 60°.
