摘要:
Toner collecting apparatus in which a toner collecting container for collecting toner remaining on the surface of a photosensitive drum in a copying machine or a facsimile machine is provided, at the lower side thereof, with a toner receiving port, a sponge roller for rotatingly feeding collected tone disposed adjacent the toner receiving port, and an optical detector for detecting that a predetermined amount or more toner has been collected in the toner collecting container. The optical detector, is disposed on the toner collecting container. At least those portions of the toner collecting container located opposite to the optical detector are made of a light-permeable material.

A cleaning device in an image-forming machine. A supporting frame structure includes a toner recovery box receiving space and a toner recovery box to be inserted into the receiving space. A toner inlet extending in the front-rear direction is formed in the toner recovery box. The cleaning device further includes a cover for recovering or closing the toner inlet at the time of withdrawing the toner recovery box from the receiving space, thereby preventing scattering of toner from the toner inlet.

A cleaning unit for an electrophotographic copier is provided to remove toner and developing material from a photo-sensitive material from which a developed image has been transferred and includes a housing having an opening facing the photo-sensitive material. A main blade member is provided in the housing of the cleaning unit and has an upper portion which abuts against the photo-sensitive material through an opening of the housing to scrape the toner and developing materials off the photo-sensitive material. The cleaning unit further includes a receiving blade covering the lower portion of the opening, and having an upper end portion abutted against the photo-sensitive material to allow the toner and developing material scraped off by the main blade to fall into the opening and a film-shaped reinforcing member bonded to the surface of the receiving blade facing the inside of the housing to prevent deformation of the receiving blade.

An image forming apparatus including an operation panel has, as a configuration of the operation panel, a display portion including a function to display environmental label information of the image forming apparatus. The environmental label information includes information on a type of greenhouse effect gases (CO2) and a total emission amount of the greenhouse effect gases in a life cycle of the image forming apparatus. On the display portion, a selective display portion for displaying an environmental label as list display or thumbnail display, as well as selectively displaying detailed information of the environmental label according to the environmental label.
摘要:
A waste developer collecting device included in a color tandem image forming apparatus which forms an image using K (black), C (cyan), M (magenta), and Y (yellow) developers includes a collecting container which can be attached to a developing device storing the C developer, a developing device storing the M developer, and a developing device storing the Y developer at the same time and which collects the C, M, and Y developers discharged from the respective developing devices. With this, it is possible to efficiently discharge and collect the developers.
摘要:
A toner transport device includes a toner transport path for passing toner, and a toner transport pipe disposed so as to have an up-and-down direction in which the toner transport path extends. Further, the toner transport device includes a pipe supporting member for supporting the toner transport pipe, which is supported so as to move up and down. This allows the toner transport pipe to vibrate up and down, thereby properly preventing retention and solidification of toner inside the toner transport path.
摘要:
A particle discharge apparatus includes cylindrical particle discharge unit(s) having toner dispensing outlet(s) provided at upper portion(s) on one side of particle discharge unit(s), and particle discharge outlet(s) provided at lower portion(s) on the other side of particle discharge unit(s); and conveyor screw(s), provided at the interior of particle discharge unit(s), having rotatable shaft(s) and helical conveyor vane(s) secured to rotatable shaft(s). The conveyor vane(s) is/are divided into first vane segment(s) and second vane segment(s); and wherein there is/are vaneless region(s), where no portion of conveyor vane(s) is present, between first vane segment(s) and second vane segment(s).
摘要:
A developing apparatus is equipped with a development casing, a development roller, and developer stirring shafts that rotate together with the development roller. In this developing apparatus, the developer stirring shafts are disposed adjacent to each other and are also disposed substantially in parallel with the development roller. Each developer stirring shaft has a rotational axis that rotates together with the development roller and has a plurality of stirring vanes of an approximately elliptic shape laid out at a predetermined angle with respect to the rotational axis. The rotational axis is provided substantially in parallel with the development roller. The stirring vanes are disposed substantially in parallel with each other, with the opposing stirring vanes between the adjacent developer stirring shafts having mutually different installation positions in the axial direction.
