摘要:
There is described a controlling method to be employed in a printing system that includes: a plurality of image forming apparatuses, each of which is capable of assigning a name to setting information in regard to a printing operation and also capable of registering the setting information in association with the name thereof; and a specific apparatus to be coupled to the plurality of image forming apparatuses. The method includes: acquiring plural sets of setting information, each of which is the setting information registered in each of the plurality of image forming apparatuses in association with the name thereof; determining whether or not at least two of the names assigned to the plural sets of setting information are cognominal; and displaying a message, indicating a fact that the same name is assigned to at least two of the plural sets of the setting information, when the names are cognominal.

Developer material remaining on an image bearing member after transfer are collected by a developer. A cleaning member is arranged between a charger and an exposure in contact with the image bearing member, for collecting the residual developer material. A bias controller controls biases to be applied to a cleaner, a charger, and a developer. During an image forming process, the biases are so determined that the residual toner on the image bearing member is collected by the cleaner. While the image forming process is not performed, the biases are so determined that the collected toner is removed from the cleaner to the image bearing member and then collected by the developer.
摘要:
An image forming apparatus having a developing device which develops an electrostatic latent image formed on an electrostatic latent image carrier to obtain a visible image. The developing device includes a charge erasing member that erases the electrical charge of residual toner on a developing agent carrier by a charge erasing bias voltage applied thereto. When exposure or not developing is not performed in the image forming apparatus, the charge erasing bias voltage is applied to the charge erasing member. While, during exposure or developing, the charge erasing bias voltage is not applied to the charge erasing member for preventing leaks or discharge phenomenon between the charge erasing member and the developing agent carrier.

An image forming apparatus accommodates a developing bias power unit for applying a bias voltage to a developing sleeve confronting a photosensitive member. The developing bias power unit includes a DC power source, an electricity storage element interposed between the DC power source and the developing sleeve, and a controller for on-off controlling the DC power source. When an output of the DC power source is activated, the electricity storage element is electrically charged by an output voltage of the DC power source, and a first voltage is applied to the developing sleeve. In contrast, when the output of the DC power source is deactivated, a second voltage of reverse polarity is applied to the developing sleeve by electric charge held in the electricity storage element.

If a user's instruction concerning at least one of print interruption and print cancellation is received by one of a plurality of printers while a print job is being executed split among the plurality of printers, a command for causing other printer that is executing printing processes based on the print job corresponding to the printing to execute a processes corresponding to the instruction is issued from the one of the plurality of printers.

In merging the printing data of the merger source to the printing data of the merger destination, the setting information concerning the tab sheets are identified from the both printing data and the aligning process is executed for aligning the tab setting information of the both printing data. For example, the tab positions are changed and aligned in such a way that the tab positions vary sequentially from the start side of pages.

摘要:
Cleaning effectiveness is improved, and inadequate charging of the photosensitive member due to soiling of the charging brush as well as image noise such as background fog are suppressed by a developing device capable of recovering residual toner regardless of the toner charge polarity. In an image forming apparatus provided with a developing device including a developing sleeve for developing an electrostatic latent image on photosensitive member via toner and recovering residual toner from the surface of photosensitive member, a power unit is provided for forming a direct current electric field between photosensitive member and developing sleeve during developing, and forming alternating current electric fields between photosensitive member and developing sleeve 16 during cleaning of residual toners.
摘要:
A voltage that has a difference in potential in the polarity direction opposite to the charge of the developer relative to the voltage applied to the sleeve by power supply 34 is applied to the control member by power supply 36. By this use of power supply 36, when the amount of remaining developer has fallen to a prescribed level, the conveyance of the developer to the photosensitive member by the sleeve is prevented, preventing image formation. Therefore, the image formation operation does not continue where the amount of remaining developer is small, which in turn eliminates the scattering of developer and maintains the cleanliness of the interior of the apparatus.
