Abstract: A liquid crystal, particularly a ferroelectric liquid crystal, is interposed between an electroconductive member and an electric charge accepting member to form a liquid crystal device. In the first step of image formation, a uniform polarity of charge is imparted to the entirety or a part of the electric charge accepting member whereby the liquid crystal is uniformly oriented to its first stable state under a uniform electric field thus formed therethrough. In the second step, the reverse polarity of charges are given imagewise to the charge accepting member, whereby the liquid crystal is reoriented imagewise to the second stable state to form an image.

Abstract: A novel image recording system using particulate developer. The particulate developer is accumulated in a container. A developer carrying member is disposed movably in contact with the accumulated developer. At the position where the particulate developer is to be flowed out from the container onto the carrying member there is provided a gate member. An important feature of the invention resides in the function of this gate member. To the gate member is given an action force which normally intends to block the flow of the developer from the container to the carrying member. Only when a record of image is formed, the developer is imagewisely put on the carrying member against the blocking force thereby forming a recorded image on the carrying member at the downstream side of the gate member.

Abstract: This specification discloses a method of making the grid of a corona discharger device and a method of mounting the corona discharger device on an apparatus body, and more particularly a method of easily forming a number of grids and a method of mounting a corona discharger device having such grids on an apparatus body. The grid making method of the present invention comprises winding an electrically conductive thin wire on a rotatable body, fixing the wound thin wire in the direction of the rotational axis of the rotatable body, fixing the wound thin wire in the direction of the rotational axis of the rotatable body by means of fixing members, and cutting the thin wire in the direction of the rotational axis. The method of mounting a corona discharger having a number of grids with respect to an apparatus body enables the grids to be highly accurately mounted with respect to the surface of an electrically charged member by using the surface of a grid supporting member which faces the charged member as the standard surface for determining the distance between the surface of the charged member and the surface of the grid supporting member.
