Provided is an image forming apparatus, in which liable to produce remaining curl, highly effective curl correction is performed. The image forming apparatus includes: a roll receiving portion for receiving a continuous recording sheet wound into a roll shape; a sheet transporting portion for transporting the continuous recording sheet from the roll receiving portion; a cutting portion for cutting the continuous recording sheet sent out into a desired size; an image forming portion for forming a toner image on the recording sheet (which has been cut); a fixing portion for fixing the toner image to the recording sheet by heating the recording sheet on which the toner image is formed; a cooling portion for cooling the recording sheet to which the toner image has been fixed; and a curl correcting portion for correcting a curl of the recording sheet when the recording sheet is cooled.

Image forming apparatus

An image-forming material removing apparatus capable of continuously peeling image-forming material such as toner from the recording medium while, with simple structure, maintaining high quality will be provided. The image-forming material removing apparatus for removing the image-forming material from a recording medium on which the image-forming material containing hot-melt resin has melted and adhered, comprising: an image peeling member provided with an image peeling layer containing hot-melt resin on the surface of a heat-resisting base material; a first heating member for heating the image peeling layer into a softened or molten state; a contacting unit that causes the image peeling layer which has been heated by the first heating member and brought into a softened or molten state to come into contact with a recording medium onto whose surface the image-forming material has adhered; a separating unit that separates the recording medium from the image peeling layer in a state in which the image-forming material adhered to the image peeling layer has been moved onto the surface thereof; and a second heating member for heating the image peeling layer separated from the recording medium into a molten state.

Image-forming material removing apparatus

The present invention discloses an image recording member in which a layer containing a setting type silicone resin having a Knoop hardness number of from 1 to 145 on the surface of a substrate made of paper, plastics or the like. Furthermore, this invention discloses a method for recycling an image recording member comprising the steps of contacting the image recording member with the outermost surface of an image releasing member, the outermost layer being formed from a pressure-sensitive adhesive or the like such as hot-melt silicone resin, heating these material and member to transfer a toner from the image recording member to the image releasing member, and separating the image recording member from the image releasing member. Thus, the invention can maintain good fixing of an image forming material with respect to the image recording member, while the image forming material can be removed from the image recording member without damaging the recording surface.

Image recording member and method for recycling image recording member

The present invention relates to a method and apparatus for reusing an image recording material wherein a releasing property is imparted to at least a substrate surface of an image recording material on which an image has been formed of an image forming material containing a heat fusible ingredient, a heat fusible material is added or attached onto the image recording material, a stripping member is contacted under pressure with the heat fusible material while heating the heat fusible material together with the image recording materials to fuse, and the image recording material is peeled off from the stripping member to transfer the image forming material together with the heat fusible material to the stripping member, thereby reusing the image recording material.

The development apparatus of this invention includes a developer supporting body consisting of a rotatable non-magnetic sleeve and a magnet roll fixedly installed within the rotatable non-magnetic sleeve. The development method involves the following steps: a latent image formed on a latent image supporting body is developed or made visible with a two-component developer carried on the developer supporting body in a non-contact manner; a horizontal magnetic field which is orientated in the circumferential direction of the developer supporting body is applied to the developer in an effective development area on the developer supporting body, the effective development area facing the latent image supporting body; and a developer movement promotion magnetic field is applied locally to a part of the effective development area on the developer supporting body so that the developer is expelled from that part of the effective development area and that chains of carrier of the developer in the developer expelled region are slid in the circumferential direction of the developer supporting body. This development method ensures a sufficiently high development performance during the multicolor image forming process without disturbing the toner image formed.
