An image forming apparatus includes a detection unit configured to detect an object, a reception unit configured to receive an operation of a user, and a shifting unit configured to shift, if the detection unit detects an object, a power state of the image forming apparatus from a first power state to a second power state different from the first power state, and shift, if the reception unit receives an operation of a user, the power state of the image forming apparatus from the second power state to the first power state.

When sheets having the same surface property and grammage are registered on a size basis, adjustment value registration operations need to be repeated for the respective sheets as many as these sizes. An image forming apparatus that includes a display unit and forms an image on a sheet sets a setting value of adjustment influenced by the characteristics of the image forming apparatus upon forming an image by using a sheet, and then displays a sheet list which displays a list of a plurality of types of sheets on a display unit and reflects the set setting value on at least one sheet selected from the sheet list.

There is provided an image forming system that includes an image forming apparatus including, a first variable mechanism that varies from a first state to a second state or from the second state to the first state when physically operated by a user, a first detection unit configured to detect the variation of a state of the first variable mechanism, and a sound collection unit. The image forming system further includes a generation unit configured to generate, when the variation is detected by the first detection unit, first statistical information regarding at least one sound wave obtained by the sound collection unit in a period based on a timing when the variation is detected.

An image forming system includes an image forming unit, a housing having a top face, an operation unit freely placed on the housing top face, a touch panel, and a supporting base. The image forming unit forms an image on a sheet. The operation unit is freely placed on the housing top face and accepts a user operation for causing the image forming unit to execute image formation. The operation unit includes a touch panel having a display face on which information about the image formation is displayed and accepting touch operation performed by a user. The supporting base supports the touch panel so that an inclination angle of the display face inclined with respect to the housing top face becomes one of 5 degrees or more and 45 degrees or less when the operation unit is placed on the housing top face.

An image forming apparatus includes an image forming device and circuitry. The image forming device forms an image on a recording material. The circuitry executes image quality adjustment control for adjusting image quality of the image formed by the image forming device. The circuitry is configured to selectively execute a first control mode for executing first image quality adjustment control and a second control mode including both the first image quality adjustment control and second image quality adjustment control. The circuitry executes only the second image quality adjustment control without executing the first image quality adjustment control in a case in which an execution skip condition for skipping the first image quality adjustment control is satisfied even when an execution condition for executing the second control mode is satisfied.

An image forming system includes: an image former that forms a label image on a long sheet conveyed in a sheet conveyance direction on a basis of a print job; an image defect detector that detects an image defect of the label image that is formed; and a sheet conveyer that conveys the long sheet in accordance with the label image where the image defect is detected after execution of the print job has been completed.

An image forming apparatus includes a first casing, a second casing, a support portion, an indication, and a USB port. The first casing includes a sheet discharge tray disposed at a top surface thereof. The indication is located at a portion of one of the top surface of the first casing and the support portion, and is positioned outside the sheet discharge tray in a width direction. The portion is located closer to one end of the image forming apparatus in the width direction than the other end of the image forming apparatus opposite to the one end in the width direction. The USB port is disposed at a portion of one of the second casing and the support portion closer to the one end than the other end in the width direction, and is located at a different position in an up-down direction from the indication.

An image forming apparatus includes a placing portion onto which a recording medium having an image formed is to be placed, and an opening-closing member that covers an opening provided at least at one side face of the placing portion and automatically opens the opening with a predetermined timing.

An image forming apparatus includes a main body including a display, a drum cartridge configured to be mounted to the main bod, a toner cartridge configured to be mounted to the drum cartridge, and a controller. The drum cartridge includes a photosensitive drum, a developing chamber configured to accommodate toner, and a drum memory. The toner cartridge includes a housing configured to accommodate the toner. The controller is configured to store, in the drum memory, a cumulative toner receiving amount which is a cumulative amount of the toner supplied from the toner cartridge and received in the developing chamber, a cumulative toner consumption amount which is a cumulative amount of the consumed toner, and a cumulative drum printing sheet number which is a number of sheets on which an image is formed.

A printing system includes a printing unit, an operation unit, and a control unit. The printing unit prints an image on a sheet, conveys the sheet to a reading unit, and performs adjustment for printing an image on the sheet based on an image read by the reading unit. The control unit performs an operation of controlling to execute a manual adjustment function for adjusting predetermined adjustment items based on adjustment values received via the operation unit after authentication of an operator. The control unit performs another operation of controlling to execute an automatic adjustment function for adjusting the predetermined adjustment items based on the image read by the reading unit without the authentication of the operator.
