According to an embodiment, an image forming apparatus displays a questionnaire regarding an apparatus on a control panel. The image forming apparatus acquires answer data to the questionnaire from a user via a touch panel of the control panel. The image forming apparatus acquires related data regarding the apparatus. The image forming apparatus associates the related data with the answer data to transmit the answer data and the related data to another apparatus different from the apparatus.

Information processing of user feedback using image forming apparatus

An image forming apparatus includes a wireless tag communication device configured to communicate with a wireless tag attached to a sheet, a fixing device configured to fix a toner image on the sheet, and a processor configured to: upon receipt of a print job, control the communication device to read from the wireless tag a first fixing temperature that has previously been used to fix a toner image on the sheet, determine a second fixing temperature to be used by the fixing device based on the first fixing temperature, and execute the print job by controlling the fixing device to fix a toner image on the sheet at the second fixing temperature.

Image forming apparatus, image forming method, and program

An image forming apparatus includes an interface and a control circuit. The interface is configured to connect a contactless card reader. The control circuit is configured to acquire identification information read from an information recording medium by the contactless card reader and to decrease a field intensity level of the contactless card reader in response to a success of authentication of the identification information.

Image forming apparatus with power saving features

According to one embodiment, an image forming apparatus includes a printer unit that includes a driving member related to the supply of the developer, a storage unit that stores correction information regarding the correction of a supplied amount of the developer and a remaining amount of the developer, and a control unit. The control unit acquires driving information regarding the driving of the driving member. The control unit acquires the correction information in accordance with the remaining amount of the developer and estimates the remaining amount of developer based on the driving information and the correction information when the remaining amount of the developer stored in the storage unit satisfies a predetermined condition regarding the remaining amount, and estimates the remaining amount of the developer based on the driving information when the remaining amount of the developer stored in the storage unit does not satisfy the predetermined condition.

Image forming apparatus and method conditionally estimating remaining toner using correction information

According to one embodiment, the image forming apparatus includes a storage unit, an image forming unit, a first electrode, a second electrode, a to-be-detected unit, a moving unit, a measuring unit, and a processor. The storage unit stores a recording material. The image forming unit forms an image with the recording material supplied from the storage unit. The to-be-detected unit is in the storage unit and is movable so that at least one of the distance to the first electrode and the distance to the second electrode changes. The moving unit moves the to-be-detected unit in the storage unit. The measuring unit measures the capacitance between the first electrode and the second electrode. The processor controls the image forming unit based on the abnormality detected based on the capacitance.

According to one embodiment, there is provided an image forming apparatus including an image forming unit and a controller. The image forming unit is able to execute a first image formation processing using a first color material and a second image formation processing using a second color material. The controller performs image quality stabilizing processing for the first image formation processing using second color material.

Image quality stabilization processing

An image forming apparatus according to an embodiment includes a first image forming unit that forms an image on a sheet using a decolorable color material for a decolorable image forming job. A second image forming unit forms an image on a sheet using a non-decolorable color material for a non-decolorable image forming job. A heat source heats the sheet at a control temperature according to a job type. A storage unit includes a job queue that registers jobs in a received order. When a plurality of jobs that differ in the control temperature are registered in the job queue, a controller that changes an execution order of the jobs in the job queue into the ascending order of the control temperature of the heat source, and executes the jobs registered in the job queue according to the changed order.

According to an embodiment, an image forming apparatus includes an image forming unit that forms an image on a sheet. A heat source heats the sheet at a control temperature according to a job type. A storage unit includes a job queue that registers jobs in a received order. When a plurality of jobs that differ in the control temperature are registered in the job queue, a controller groups the jobs registered in the job queue into job groups according to the control temperature. The controller also changes an execution order of the job groups in the job queue into the ascending order of the control temperature of the heat source, and executes the jobs registered in the job queue according to the changed order.

According to an embodiment, an image forming apparatus includes a job queue that registers jobs and a controller that executes the jobs according to an order in which the jobs are registered in the job queue. Further, when a plurality of jobs that differ in a control temperature of a heat source are registered in the job queue, the controller sorts the jobs in the job queue so that a required time until execution of all the jobs is completed becomes shortest.

In accordance with one embodiment, an erasing apparatus includes a paper feed tray configured to feed a sheet, a reading unit configured to read an image on the sheet, an erasing unit configured to erase the image on the sheet, a cutting apparatus configured to cut the sheet allowed to be cut, a reject box configured to accumulate the sheet which is judged to be not-reusable and a control unit configured to judge the category of the sheet based on the output of the reading unit and change the conveyance destination of the sheet according to the category of the sheet.

Erasing apparatus and erasing method

An image forming apparatus includes: a display section to display plural patterns having the same shape and different tints on the same screen; a selecting section which a user selects a desired pattern from the plural patterns displayed on the display section; a determining section which the user inputs a determination concerning whether the desired pattern selected with the selecting section is suitable; and a control section to set, according to the input to the determining section, a tint of a toner image formed by an image forming section.
