摘要： An inside contamination preventing mechanism is provided that is adapted to be positioned in an imaging apparatus utilizing an electrophotographic system for forming an image on a predetermined recording medium and having an air directing mechanism including an air intake portion through which air flows from the outside of the imaging apparatus and a driving member for driving the air to a predetermined portion through a predetermined area within the imaging apparatus, and a toner containing member that is located adjacent to the air intake portion for containing the toner particles remaining in the imaging apparatus after an imaging operation onto the predetermined recording medium. The inside contamination preventing mechanism includes a cover member provided on an inner surface of the imaging apparatus for covering an opening of the toner containing member. Thus, it becomes possible to prevent the toner from floating in the air, and accordingly, it becomes possible to keep the inside of the imaging apparatus clean.

摘要： In an image fixing apparatus, a fixing roll unit is arranged in a predetermined path along which a continuous form travels, for applying pressure and/or heat to an image on the continuous form to fix the image thereonto. An endless belt member is arranged upstream of the fixing roll unit with reference to a transport direction in which the continuous form travels along the predetermined path. The endless belt member has provided thereon a plurality of projections arranged in spaced relation to each other along an outer periphery of the endless belt member. The projections are engageable with sprocket holes formed in the continuous form along opposite side edges thereof. The endless belt member is capable of running in the transport direction while applying a predetermined back-tension to the continuous form traveling toward the fixing roll unit along the predetermined path.

摘要： An electrophotographic printer is capable of using a plurality of types of continuous form recording media having different page lengths, respectively. In the printer, a photoconductive member is charged and exposed to light carrying image data to form a latent image. In operation, one of the plurality of types of recording media is selected, and a portion of the photoconductive member corresponding to a page of the selected one of the plurality of types of recording media is exposed to light. In another embodiment, a laser beam printer utilizes a continuous-form recording sheet, wherein two control members are provided for, respectively, controlling the recording sheet so as to be discharged from the printing device after a printing operation, and for controlling the recording sheet so as to be located at a position from which a printing operation is restarted. Thus, recording sheets are not wasted when printer output is started.

摘要： A justification system is provided for use in an electrophotographic printer. The justification system comprises a detector which detects the passage of individual segments of a continuous form which are being fed at a predetermined rate. A counter counts the number of main scannings of a laser beam carrying printing information over the surface of a photoconductive drum. A read control is connected to the detector and the counter and controls reading of main information stored by monitoring outputs from the detector and the counter so that printing of each segment always occurs at a predetermined position, synchronously with passage of the segments.

摘要： A heat roll fixing device for an electrophotographic image recording apparatus is provided with a cleaning felt extending in the axial direction of the heat roller and arranged to contact the circumferential surface of a heat roller for removing toner thereon with oil being oozed from the cleaning felt and applied to the circumferential surface of the heat roller. In order to evenly spread or absorb the oil, it is particularly applied onto the circumferential surface of the heat roller while it is located at its retracted position when printing operation is started, with the heat roller being controlled to rotate for a predetermined period of time before being shifted to its operable position. Then the rotation is stopped and the heat roller is shifted to the operable position. The rotation of the heat roller is restarted after another predetermined period of time has passed since the required operation of the image recording apparatus.

摘要： A storage vessel detecting mechanism is used for detecting an error condition of a storage vessel, which is detachably fitted in a main apparatus. The vessel is movably fitted in the main apparatus, and one end of a movable member, which is pivoted, is engaged with the vessel. The other end of the movable member is located between first and second positions when the vessel is not installed and when the vessel is accommodating a predetermined amount of substances therein. It is determined whether the other end of the movable member is located in a predetermined range. An error condition of the vessel is detected when the other end of the movable member is located at a position other than in the predetermined range.
