Abstract: An electrostatic latent image is formed on a rotatable latent image bearing member and is developed with a developer into a visualized image on the latent image bearing member. The visualized image is transferred by pressure to a rotatable visualized image bearing member.

The latent image bearing member and the visualized image bearing member are cooperative to form a nip therebetween, through which a recording material is passed so that the multi-color image is transferred all at once to a recording material. The multi-color image may be a full-color or pictorial image or a combination of monochromatic images of different colors.

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.
