摘要:
This invention relates to a liquid developer monitoring device comprising a first electrode which contacts with a liquid developer comprising a liquid medium and electrically charged toner particles dispersed therein, a second electrode being either a developing roller or a separate roller which provides a fresh surface and immerses said surface in the liquid developer, an electric power source which applies a bias voltage between said first and second electrodes so as to deposit the toner particles on the second electrode, and a sensor which measures magnitude of current flowing between said first and second electrodes during the deposition of the toner particles. A cleaning device removes the deposited toner on the second electrode. The sensor includes an electric coil, a magnet inserted in the coil and a Hall element.

Upon reception of a job, a control unit of an image processing apparatus executes processing for judging whether any cancellation factor exists. If there is no cancellation factor, the control unit outputs pages relating to the job, stores page information thereof, and updates execution history information after outputting all the pages. If there is any cancellation factor, the control unit performs only preparation for output of the pages, stores page information obtained through the preparation, and updates cancellation history information after storing the page information of all the pages. A message as a result of evaluation of the cancellation history information is displayed on an operation panel. The message prompts an administrator to change management condition as needed.

In an image processing apparatus connected to an external apparatus through a network, a user interface is displayed in a display device on documents. A user's instruction is received in the user interface to operate a document stored in the external apparatus and/or in the image processing apparatus. An operation history of documents stored in the external apparatus is obtained. Then; data on the documents displayed in the user interface is controlled based on the obtained operation history.

When a user select a file to be processed from a box present in an image formation apparatus a feature of the selected file is extracted. A feature point recording region is searched and data of a previous execution history of a file having a feature point matching that of the selected file is called and displayed. Therefrom the user selects an operation that the user desires to execute for the selected file.
摘要:
An image forming apparatus includes a first developing device, accommodating a first kind of toner without an offset preventing agent, a second developing device accommodating a second kind of toner containing an offset preventing agent, and a roller fixing device having a supply portion for supplying an offset preventing agent. The image forming apparatus changes the amount of the offset preventing agent to be supplied to the fixing roller between the case of fixing a copy image formed with the first kind of toner and the case of fixing a copy image formed with the second kind of toner.
