摘要:
An image-receiving member of sheet material has a portion on which a positive image is adapted to be formed. A pod of processing liquid is secured to the sheet material outside of the image-forming portion. Each pod is preferably divided into two processing fluid containing portions, such that an advancing roller can contact the flat portion devoid of processing liquid in order to advance the image-receiving sheet without rupturing the pod. The mask defining the area on which a positive image is formed, can be either a continuous sheet having openings at regular intervals, or it can be formed by connector sheets alternately coupled to image-receiving sheets in combination with longitudinal masking strips affixed directly to the image-receiving sheet.

An instant camera in which a self-processing type film unit is passed between a pair of spreading rollers and ejected to the exterior of the camera while a container means containing a development processing solution in the film unit is torn by the nipping force of the rollers causing said processing solution to be spread over an image forming region in said film unit, characterized by the spreading rollers being formed such that the clearance therebetween is greater at the center section thereof and smaller near the roller ends which contact the edges of said image forming region.

A blade includes an elastic member including a tip ridgeline to contact the surface of a member to contact. The tip ridgeline includes an impregnation layer impregnated with a cured compound comprising an acrylate or methacrylate compound having an alicyclic structure including 6 or more carbon atoms in its molecule, and has an elastic power in the range of 50% to 80%.

A developing device includes a first screw that supplies a developer to a developing roller while agitating/conveying the developer in a first direction, and a screw that collects residual developer from the developing roller, agitates/conveys the residual developer in a second direction opposite to the first direction, and delivers the residual developer to the first screw. Between two points that a magnetic flux density in a normal direction of a magnetic field formed in a developer separating magnetic pole in the developing roller become substantially zero, a point at a downstream side in a rotating direction of the developing roller is formed at an upstream side to a developing roller rotating direction, than a line joining the center of the developing roller and the center of the second screw.

A fixing belt is heated by electromagnetic induction. The fixing belt has a heat generating layer that has a thickness not greater than 40 μm and a releasing layer that has a thickness not less than 10 μm. A toner that includes at least a binder resin, a colorant, and a mold releasing agent, and has a glass transition temperature in a range of 35° C. to 50° C. and an outflow-start temperature in a range of 80° C. to 110° C., is used.
摘要:
An image forming apparatus of the present invention includes a fixing device for fixing a toner image formed on a recording medium. A heat source is applied with power for generating heat to thereby heating the heating device. A drive circuit includes a storage capable of being selectively charged or discharged and a charger for charging the storage by being supplied with power from a commercial power supply. A discharging device discharges the storage in a non-use mode in which the apparatus is not used.
摘要:
A fixing device including a fixing belt, a drive roller and a press roller. The drive roller is configured to drive the fixing belt, and press roller is arranged so as to face the drive roller across the fixing belt, and exert pressure toward the fixing belt. The drive roller and the press roller are able to rotate so that the peripheral velocity of the drive roller is greater than the peripheral velocity of the press roller. According to the fixing device image defects, including image difference, are less likely to occur when fixing an image on a recording sheet.

An image-fixing apparatus including a fixing belt; a fixing member; a pressure member; and a heating source, wherein the fixing belt is heated by the heating source, wherein the fixing member is brought into pressure contact with the pressure member via the fixing belt to form a nip and a paper carrying an unfixed toner is allowed to pass through the nip, thereby fixing the unfixed toner on the paper, and wherein the toner to be used includes a binder resin, a colorant, and a releasing agent, and wherein the toner has a ½ flown-out temperature of 115° C. to 145° C. and has a storage elastic modulus (G′) at 190° C. of 200 Pa or more.
摘要:
A transfer-fixing unit for use in an image forming apparatus having an intermediate transfer member and a transfer-fixing unit, which includes a pressure member and a transfer-fixing member. The intermediate transfer member receives a toner image thereon. The transfer-fixing member has a deformable surface layer thereon, and directly receives the toner image from the intermediate transfer member, and transfers and fixes the toner image to a recording medium while deforming the surface layer in response to surface irregularities of the recording medium. The transfer-fixing member forms a nip portion with the pressure member and presses the recording medium at the nip portion when the recording medium passes through the nip portion with a nip time.
