摘要:
The present invention provides an image forming apparatus which, when switching operation from color image forming operation to monochromatic image forming operation, forms a monochromatic image on each of a prescribed number of sheets by stopping a part of the functions of yellow, magenta and cyan image forming sections of the color image forming operation, and thereafter, forms a monochromatic image only with a black-only image forming section, thereby permitting extension of service life of the image forming sections, while improving the productivity.

There is provided an image forming apparatus which is capable of securing a time period for measuring the base reflected light quantity required for the base correction, and at the same time, reducing a time period required for the entire image density control. An image forming unit includes an image carrier disposed to be exposed to light to have a latent image formed thereon, an electrostatic charger that charges the image carrier to a predetermined polarity, a developing device that visualizes the latent image formed on the image carrier to form a visible image, and an endless belt onto which the visible image is transferred. A CPU controls the image forming unit to form predetermined detection patterns on the endless belt. The detection patterns and the quantity of reflection light from the endless belt are detected. The CPU corrects the detected detection patterns based on the detected quantity of reflection light. One of the image forming conditions is adjusted by the CPU, based on the corrected detection result of the detection patterns. Another one of the image forming conditions is adjusted by the CPU. The detection of the quantity of reflection light from the endless belt is carried out in timing synchronous with the adjustment of the other image forming condition.

There is provided an image forming apparatus of the type that a toner image, which is transferred onto an intermediate transfer member, onto a sheet material, is transferred onto a sheet material, which is capable of reducing the possibility of leading end misalignment even if there is a delay in conveyance of the sheet material. An image forming device forms an image on a photosensitive member. An image carrier carries an image. A first transfer device transfers the image carried by the image carrier onto a sheet. A second transfer device transfers the image transferred onto the image carrier onto a sheet. A feeding device feeds the sheet. A conveying device conveys the sheet fed by the feeding device to the second transfer device. A controller controls the conveying device to cause the sheet to be temporarily stopped at a first location and a second location between the feeding device and the second transfer device. The controller is operable when determining that, if the sheet is caused to be temporarily stopped at the first location, the sheet cannot be conveyed to the second transfer device by the conveying device in time for timing in which the image carried by the image carrier reaches the second transfer device, for providing control to inhibit the sheet from being temporarily stopped at the first location.

The present invention relates to a developer replenishing mechanism in which a developer replenishing apparatus is provided with a storing container containing a developer therein and capable of discharging the developer therefrom, and detachably attachable to a main body of the developer replenishing apparatus, and a carrying member provided in the storing container for carrying the developer. A control device interrupts the discharging operation of the storing container, and thereafter resumes the discharging operation of the storing container after the storing container is detached with respect to the main body of the developer replenishing apparatus and is again attached thereto, and thereafter inhibits the developing operation of the developing apparatus and interrupts the discharging operation of the storing container when it is detected at the second time by the detecting means that the driving load is not less than the predetermined value.

In an image forming apparatus for reversing/discharging sheets on which images are formed, control is performed to form mirror images on sheets and discharge the sheets, on which the mirror images are formed, without reversing them in accordance with the type of sheet on which images are to be formed, thereby adjusting the output order of the sheets without increasing the sheet output time and causing any damage on the sheet.

In an image forming apparatus such as a copying machine or the like having a sorter with a plurality of paper ejection bins, there is provided a sorter apparatus which can efficiently execute a dividing and sorting operations for every work irrespective of a size and a direction of sheets, the presence or absence of a sheet stapler, a remaining state in the sheet sorter apparatus, or the like. A recycle automatic document feeder (RDF) for automatically feeding originals, a sorter, an aligning bar and a reference bar in a sorter bin, and the like are provided. When a length of sheet exceeds a predetermined value, the movement of the sheets by the reference bar is inhibited.

A sheet processing apparatus includes a plurality of trays for stacking sheets. A sheet shifting arrangement shifts the sheets on trays so that a portion of the sheets protrudes over the tray. A selector selects one of a plurality of processing modes for the sheets on the trays. A setting arrangement corresponding to each the processing modes manually sets whether the automatic sheet shifting by the sheet shifting means is to be performed. A controller controls the sheet shifting arrangement in accordance with the contents set by the setting arrangement and the processing mode selected by the selector, wherein with respect to the processing mode selected by the selector means, the controller automatically operates the sheet shifting arrangement in accordance with the automatic sheet shifting set by the setting arrangement and does not operate the sheet shifting arrangement in accordance when automatic sheet shifting is not set.

In a process of crosslinking a rubber compound with the usage of an organic peroxide as the crosslinking agent, is incorporated to the rubber compound in an amount of 0.5-20 parts by weight per 100 parts of a rubber substrate a compound selected from imidazole type compounds, thiourea type compounds, thiazole type compounds, thiuram type compounds, dithiocarbamate type compounds, phenol type compounds, triazole type compounds and amine type compounds. The process results no surface tackiness of the rubber product crosslinked in the presence of oxygen.

A sheet stacking apparatus includes a discharge unit, a stacking tray, an acquisition unit, a shift control unit, and an alignment unit. The shift control unit controls a stacking position of a sheet in a sheet width direction in response to shift information acquired by the acquisition unit. The alignment unit aligns a sheet staked on the stacking tray and moves to a position that abuts on a side edge of the sheet in the sheet width direction to align the sheet. The shift control unit controls a stacking position of a second sheet to stack the second sheet on a second position or on a first position depending on where a first sheet is stacked and on shift information of the second sheet.
