An image forming apparatus is configured such that in a case where images are to be formed on a first surface of a preceding sheet, on a first surface of a succeeding sheet fed to the first conveyance path succeeding to the preceding sheet and on a second surface of the preceding sheet, a first conveyance member is stopped without reversing the preceding sheet to a second conveyance path in a case where the image has been formed on the first surface of the preceding sheet and permission of preparing the image to be formed on the first surface of the succeeding sheet is not issued yet, and the first conveyance member restarts conveyance of the preceding sheet to the second conveyance path based on timing when an image forming unit starts preparing the image to be formed on the first surface of the succeeding sheet.

A circuit board for an image forming apparatuses to which a first integrated circuit or a second integrated circuit is provided, comprising an electric part provided to a first surface of the circuit board, a first attachment part provided to the first surface, to which at least one terminal of the first integrated circuit is attachable, a first conductor pattern formed on the first surface and configured to constitute at least a portion of a first wiring which connects the first attachment part and the electric part, a second attachment part provided to a second surface opposite to the first surface of the circuit board, to which at least one terminal of the second integrated circuit is attachable.

A device including a replaceable component, in which the component is not electrically connected to the device and includes a component-side storage, a component-side transmitter/receiver, a component-side hardware processor, and a component-side power generator, the device includes a main-body side storage, a counter which counts up the consumption degree of the component stored in the main-body storage, a main-body side transmitter/receiver, a main-body side hardware processor, a main-body side power generator, and a detector which detects attachment and detachment, the main-body side hardware processor causes the main-body side transmitter/receiver to transmit the specific identification information of the component and the consumption degree of the component when detachment is detected, and the component-side hardware processor rewrites the information in the component-side storage on the basis of the specific identification information of the component and the consumption degree of the component.

An apparatus includes: a unit that provides an instruction on creasing and folding positions on paper set such that the distance between fold crease and fold line positions is meaningful; a unit that acquires a read image by reading paper that has been subjected to creasing and folding processes in accordance with the creasing and folding positions in an open state; a unit that analyzes the read image to detect two streaks corresponding to the fold crease and the fold line from the read image, and that specifies the position of one of the two streaks as the fold crease position and the position of the other as the fold line position on the basis of the creasing and folding positions; and a unit that outputs correction information about at least one of the creasing and folding positions such that the fold crease and fold line positions match each other.

Various embodiments include an image forming unit configured to form an image on a recording material, an illumination unit configured to emit light, an image capturing unit configured to capture light emitted by the illumination unit and reflected by the recording material as a surface image including a plurality of pixels, and a control unit configured to calculate a first feature quantity from a difference of output values of a plurality of pixels arranged in a first direction, and calculate a second feature quantity from a difference of output values of a plurality of pixels arranged in a second direction intersecting the first direction in the surface image captured by the image capturing unit, and control an image forming condition of the image forming unit based on the calculated first feature quantity and the calculated second feature quantity.

An image forming apparatus includes an image forming portion, a fixing device detachably mounted on a main assembly of the image forming apparatus and a moving mechanism. The fixing device includes a detecting flag contacting a back surface of the recording material. The detecting flag is positioned in a first position within a conveyance path when the recording material does not exist on the detecting flag and moves in a direction toward the back surface from a front surface relative to the first position when the recording material exists on the detecting flag. The moving mechanism causes the detecting flag to move so as to position the detecting flag in the first position when the fixing device is mounted on the main assembly and in a retracted position when the fixing device is demounted from the main assembly.

An image forming apparatus includes a housing, a feeding tray inserted into and pulled out from the housing, an image forming unit, and first and second guide members. The feeding tray includes a first accommodation part in which a roll body having a configuration where a sheet-shaped medium is rolled in a roll shape is accommodated and a second accommodation part in which stacked sheet-shaped media are accommodated. The first guide member guides a sheet-shaped medium to a conveying path. The second guide member guides a roll medium unrolled from the roll body to the conveying path. The second guide member is movable between a guide position for guiding the roll medium to the conveying path, and a retreat position further distant from the first guide member than the guide position and where the second guide member does not interfere with a sheet-shaped medium accommodated in the second accommodation part.
