Technical Examples
- A developing cartridge includes a casing having a toner chamber, a feeding roller installed within the toner chamber, a developing roller supplied with a toner from the feeding roller, and a sealing film interposed between the developing roller and the feeding roller. The sealing film blocks a movement of the toner toward a gap between the developing roller and a bottom of the toner chamber, so that the toner does not leak out through the gap between the developing roller and the bottom of the toner chamber.
- A photographic light-sensitive material having a support having a thickness of from 160 to 225 ?m is processed with an automatic developing apparatus, in which at least one of rollers of a developing part, a fixing part and a rinsing rack part of the automatic developing apparatus has a surface mainly containing a nonpolar polymer substance and having a center line surface roughness (Ra) of 20 ?m or less. By using the automatic developing apparatus, dusts generated in the apparatus can be easily removed with a cleaning film.
- A photo-thermographic recording apparatus, comprises a film loading device capable of loading a sheet type photo-thermographic film, a conveyance device for conveying the photo-thermographic film from the film loading device, an exposing device for forming a latent image corresponding to an image signal onto the sheet type photo-thermographic film conveyed by the conveyance device, and a thermal developing device for visualizing the latent image formed onto the sheet type photo-thermographic film while heating the sheet type photo-thermographic, the thermal developing device including a heating device therein and a plurality of opposed rollers arranged opposite to the heating device so as to press the sheet type photo-thermographic film onto the thermal developing device, herein the plurality of opposed rollers is structured so that a foreign matter originating from an edge portion of the sheet type photo-thermographic film does not affect an image formed on the sheet type photo-thermographic film.
- An image forming apparatus, includes: a mainframe; a developing unit including a developing agent container that contains a developing agent and a developing agent carrier that carries the developing agent; and an image carrying unit including an image carrier that carries a developing agent image formed by an electrostatic latent image being developed by the developing agent carried on the developing agent carrier. The developing unit is attachable to and detachable from the image carrying unit. The developing unit is loadable in and unloadable from the mainframe in a state where the developing unit is integrally attached to the image carrying unit.
- In the image forming apparatus of the present invention, a developing roller is press fit into the rotor at the edge of the rotary holder of the revolver type color developing device that is positioned against the photosensitive drum and a developing gap between the photosensitive drum and the developing roller is finely adjusted in parallel to a line connecting the center of the photosensitive drum and the rotary holder by sliding the developing roller in the rotor by the adjuster. Irrespective of the adjustment of the developing gap, the developing position on the photosensitive drum is always kept at a constant position and a developing image of high level of quality is obtained.
