摘要:
A photographic apparatus for use with the peel-apart type self-developing film units contained in a cassette is provided for allowing a user to take a photograph of himself and obtain the print then and there. The apparatus includes a camera back which is moved forward for urging the cassette in order to locate photosensitive sheets of film units in the cassette in position for exposure and retracted from the cassette after, say, ten exposures. The camera back is kept retracted for a time sufficient to allow automatic supplying of a fresh film pack which is the foremost one of a plurality of film packs contained in a rack. The apparatus also includes a film unit withdrawing apparatus for automatically withdrawing an exposed film unit for providing the print to the user.

An instant photographic method uses a photosensitive member in the form of a roll, of a length to receive a plurality of exposures, and an image-receiving member in the form of either a roll or a sheet. The photosensitive member is cut off to the length of a single frame of film after the exposure of its leading end. Before or after cutting off the member or members, the exposed leading end of the photosensitive member and the image-receiving member are superposed. Between the superposed members a processing liquid is distributed and spread in a uniform layer for diffusion transfer processing. During the processing, negative and positive images are produced simultaneously on the photosensitive and image-receiving members, respectively, according to the latent image previously created on the photosensitive member by exposure.

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.

A film unit withdrawing apparatus withdraws an exposed film unit from the film pack while permitting it to pass through a pair of pressure rollers. The peel apart type film unit to be used for this apparatus is attached with a tab. This film unit withdrawing apparatus is such that after a photograph is taken, the aforementioned tab is held between and withdrawn by a tab transfer roller and a nip roller. Following the withdrawal of the tab, the pull end of the film unit is ejected by passing between the pressure rollers. Simultaneously, the tab is torn off the film unit. Subsequently, the pull end of the film unit is held between a film unit transfer roller and a nip roller, and the film unit is automatically withdrawn by passing between the pressure rollers.

摘要:
A disclosed image forming apparatus forms a toner image on a surface of a surface moving image bearing body and eventually transfers and fixes the toner image onto a recording medium to form an image on the recording medium and removes, by a cleaning apparatus, an adhered matter which is adhered to the surface of the image bearing body after the transferring. In the image forming apparatus, a glass transition temperature (Tg) of a toner is 40-60° C., and the cleaning apparatus causes a tip ridgeline portion of a blade member to be abutted against the surface of the image bearing body to remove the adhered matter from the surface of the image bearing body, and the tip ridgeline portion of the blade member is made of elastic rubber whose 100% modulus value at 23° C. is at least 6 MPa.

There is provided a pre-cleaning brush roller being a pre-cleaning member which is disposed on an upstream of a normally-charged-toner cleaning brush roller and an oppositely-charged-toner cleaning brush roller in a surface moving direction of an intermediate transfer belt, is applied with a voltage having a polarity opposite to a normal charge polarity of toner, and electrostatically removes the toner having the normal charge polarity.

A cleaning device including a normally charged toner cleaning member provided in contact with a cleaning target at a contact position to remove normally charged toner from the cleaning target, a reversely charged toner cleaning member provided in contact with the cleaning target at a contact position upstream from the normally charged toner cleaning member to remove reversely charged toner from the cleaning target, and a pre-cleaning member provided in contact with the cleaning target at a contact position upstream from both the normally and reversely charged toner cleaning members to remove normally charged toner from the cleaning target. The contact position between the pre-cleaning member and the cleaning target has a width wider than a width of the contact position between the normally charged toner cleaning member and the cleaning target and a width of the contact position between the reversely charged toner cleaning member and the cleaning target.

A cleaning device disposed downstream from a transfer position in a direction of rotation of the image carrier to remove toner from the image carrier. The cleaning device includes a normally-charged toner cleaning member to electrostatically remove normally-charged toner from the image carrier, one of a polarity controller to control the toner on the image carrier to have a normal charging polarity and a reversely-charged toner cleaning member to electrostatically remove reversely-charged toner from the image carrier, a pre-cleaning member to electrostatically remove normally-charged toner from the image carrier, a pre-collection member to electrostatically collect the toner from the pre-cleaning member, and a control unit to reduce a voltage applied to the pre-cleaning member immediately after an untransferred toner image is removed from the image carrier by the pre-cleaning member below a voltage applied to the pre-cleaning member during removal of the untransferred toner image.
