In accordance with an embodiment, an image forming apparatus comprises a printing setting acquisition section and a printer section. The printing setting acquisition section acquires printing setting information for holding setting at the time of printing for each kind of a sheet. The printer section applies, in a case in which a label paper is selected as the kind of the sheet, a developing agent in the vicinity of an area coming into contact with an end part of the sheet in an area on an image carrier for transferring the developing agent to the sheet, transfers the developing agent by a transfer member for transferring the developing agent from the image carrier to the sheet, and rotates the transfer member at least once.

An image forming apparatus includes an image bearing member; a toner image forming portion, a transfer member, a voltage applying portion, an acquiring portion, and a controller. In continuous printing in which toner images are continuously transferred onto a first recording material and a second recording material, in a case that the first recording material is an envelope on the basis of recording material information, the controller carries out control so that a transfer member cleaning operation in which a first cleaning voltage of the same polarity as a normal charge polarity of toner and a second cleaning voltage of an opposite polarity to the normal charge polarity of the toner are alternately applied by the voltage applying portion is executed after the first recording material passes through the transfer portion and before the second recording material reaches the transfer portion.

In a case where a type of a feeding standby sheet on a storage unit and a type of a refeeding standby sheet on a reconveyance path are the same, an image forming unit forms an image on one side of a feeding standby sheet on the storage unit, and in a case where a type of a feeding standby sheet on the storage unit and a type of a refeeding standby sheet on the reconveyance path are not the same, the image forming unit forms an image on another side of a refeeding standby sheet on the reconveyance path.

A media detection apparatus for detecting moisture information corresponding to a moisture amount or a moisture percentage of a sheet, the media detection apparatus comprising: a light emitter that emits light; a light receiver that receives the light reflected off the sheet or transmitted through the sheet; and a first hardware processor that determines the moisture information on the basis of temperature information corresponding to a temperature of the media detection apparatus and an output of the light receiver.

An identification apparatus includes a guide member defining a guide path, a scanning portion that scans the sheet inserted in the guide path, a first detection portion disposed upstream of the scanning portion in an insertion direction of the sheet in the guide path that detects presence/absence of the sheet, and a second detection portion disposed downstream of the scanning portion in the insertion direction in the guide path and detects presence/absence of the sheet. The identification apparatus is configured to start measurement of a surface property of the sheet by the scanning portion in response to a change in a detection result of one of the first detection portion or the second detection portion, and complete the measurement in response to a change in a detection result whichever of the first detection portion or the second detection portion not used in determining the start of the measurement.

A print control apparatus capable of communicating with a printing apparatus, including a sheet holding unit in which a sheet to be used for printing is held, for printing an image on the sheet held in the sheet holding unit includes storage configured to store a type of a sheet, an image, and a setting value of the printing apparatus in association with each other, selects a type of a sheet to be used for printing by the printing apparatus, selects an image to be printed by the printing apparatus, and sets the setting value stored in the storage in association with the selected type of the sheet and the selected image.

An image forming apparatus for forming an image designated by a job on a sheet fed from one of a plurality of paper feed sources. The apparatus includes a detection unit that detects paper types of sheets respectively fed from the plurality of paper feed sources, a detection unit provided on a conveyance path, a memory device that stores a set of instructions, and at least one processor that executes the instructions to function as a first holding unit to hold paper sizes and paper types set by a user in one-to-one correspondence with the plurality of paper feed sources, a second holding unit to hold the paper types detected by the detection unit in one-to-one correspondence with the plurality of paper feed sources, and a third holding unit to hold a paper size designated by the job and a paper type. designated by the job or a condition related to setting of a paper type.

A parameter determination apparatus includes: a first hardware processor that acquires a value related to a plurality of types of sheet physical properties; a second hardware processor that specifies at least any of a sheet type or a basis weight based on an acquired value related to a sheet physical property; and a third hardware processor that specifies a parameter related to sheet processing without specifying at least any of the sheet type or the basis weight, based on an acquired value related to a sheet physical property.

A sheet characteristic detection system that detects a sheet characteristic, includes: a sheet characteristic detection device that includes a plurality of media sensors corresponding to a plurality of different sheet characteristics; and a hardware processor that is capable of changing a type of the sheet characteristic to be detected by the plurality of media sensors.

A sheet characteristic detection device includes a first conveyance path on which a sheet is conveyed, a second conveyance path that is branched from the first conveyance path and on which a sheet to be purged is conveyed without passing through an image former, and a first detector that is disposed on the first conveyance path and allows detection of sheet characteristic information corresponding to at least one of a size, a sheet thickness, a basis weight, or a moisture amount of the sheet.
