摘要:
A toner recovery roller having at least its outer peripheral part made of an insulator and rotated and driven in a predetermined direction is disposed in the vicinity of a position where an image carrier and a developing roller interact with each other, and a triboelectric charging member for triboelectrically charging an outer peripheral surface of the toner recovery roller to a polarity opposite to that of toner particles is so provided as to be brought into contact with the outer peripheral surface of the toner recovery roller.The rotation of the toner recovery roller in a predetermined direction causes friction between the friction charging member and the insulating outer peripheral surface of the toner recovery roller, so that the insulating outer peripheral surface of the toner recovery roller is triboelectrically charged to a polarity opposite to that of toner particles. Therefore, toner particles scattered from the developing roller are attracted to the toner recovery roller to adhere thereto.A charging potential of the toner recovery roller does not immediately reach zero but remains to some extent even in cases, for example, immediately after a copying machine is stopped, when the power supply of the copying machine is turned off immediately after copying is terminated, and when a front door of the copying machine is opened by paper jamming or the like. Also in this case, therefore, floating toner particles are attracted to the toner recovery roller to adhere thereto.

An image forming machine comprising a rotating drum mounted rotatably and having a photosensitive material disposed on the peripheral surface thereof; a rotating drive source for causing the rotating drum to rotate; an image forming means for forming a toner image on the photosensitive material in an image forming zone; a transfer means for transferring the toner image on the photosensitive material onto an image receiving member in a transfer zone located downstream of the image forming zone as viewed in the direction of rotation of the rotating drum; and a cleaning means which acts on the photosensitive material in a cleaning zone located downstream of the transfer zone but upstream of the image forming zone as viewed in the direction of rotation of the rotating drum. The cleaning means includes a cylindrical brush formed of a multiplicity of radially extending yarns. The brush of the cleaning means is mounted rotatably about the central axis of rotation extending substantially parallel to the central axis of rotation of the rotating drum, is pressed against the photosensitive material, and is caused to rotate following the rotation of the rotating drum.

A nanofiber manufacturing system in which nanofiber is formed from a raw material liquid by electrostatic explosions in a nanofiber forming space and the formed nanofiber is collected and deposited on a main surface of a base sheet. The system includes: a first dielectric belt having dielectric property; sheet conveying devices for conveying the base sheet in the nanofiber forming space; a sheet contacting device putting a back surface of the base sheet and a first surface of the first dielectric belt into contact with each other; a dielectric belt driving device for running the first dielectric belt in a conveyance direction of the base sheet within the nanofiber forming space while the first surface is kept in contact with the back surface of the base sheet; and a voltage applying device for applying a voltage to the second surface of the first dielectric belt so that dielectric polarization occurs to the first dielectric belt.

A method of manufacturing a honeycomb structure having a plugged portion, which is faster and cheaper to manufacture, and a manufacturing apparatus thereof. A film is attached to an end face of a honeycomb structure in a state where the honeycomb structure is positioned in a table portion having a through hole into which the end face portion of the honeycomb structure is to be inserted, and the film is held in a flat state where a remaining portion of the film which is not attached to the end face is attached to the table portion. Then, holes opened so as to correspond to the openings of a part of cells are formed in the film to form the film as a mask, and a plugging material having fluidity is supplied onto the mask or onto the same plane as the mask to fill the cells with the plugging material.

When a print processing apparatus is in a power saving mode, an information processing apparatus informs, for the print processing apparatus, the user that the print processing apparatus is in the power saving state. It can thus be made known to the user that the print processing apparatus is in the power saving state.

This invention provides an image processing system and image processing method which can promote efficient use of a memory by vectorizing all data of a representative object and, for the same or similar object, referring to the vectorized representative object and using difference data and also convert the same or similar objects at once by editing only the representative object. Input image information is vectorized. The vector data of a representative object is stored. Identity between a target object and the representative object is determined. If the two objects are identical, property information containing information about the reference destination of the vector data of the representative object is stored in place of the vector data of the target object.

A manufacturing apparatus of a plugged honeycomb structure includes a table portion 11 having a through hole 11h into which the end of a honeycomb structure 1 is inserted, positioning means for positioning and holding the honeycomb structure 1 in the through hole 11h of the table portion 11 in such a manner that its end face 8 appears on the side of a first face 11a of the table portion, and a film holding portion 13 fixing the remaining portion of a film 25 on the side of a second face 11b of the table portion 11. After or before fixing the film 25, holes corresponding to openings of cells 3 of the honeycomb structure 1 are formed in the film, and a plugging material 31 is filled into the holes, to manufacture the plugged honeycomb structure 1, and the method of manufacturing the plugged one using the apparatus.
