An image forming system includes an image forming unit, a varnish coating unit, a reception unit, and a control unit. The image forming unit executes an image forming process of forming an image on types of recording media including a first type of recording medium with a coated layer and a second type of recording medium without a coated layer. The varnish coating unit executes a varnish coating process of varnish coating a recording medium on which an image is formed by the image forming unit. The reception unit receives a printing job from a user. The control unit controls the varnish coating unit. When the printing job received by the reception unit is a printing job for executing the varnish coating process on the second type of recording medium, the control unit controls the varnish coating unit to prevent the varnish coating unit from executing the varnish coating process.

An image forming system includes an image forming apparatus configured to form a toner image on a recording material, a varnish application apparatus configured to apply a varnish to the recording material, and a control unit. The control unit is configured to apply a first application amount of varnish to the recording material per unit area in a case of executing the image forming job for forming a varnish layer on a recording material having a first grammage, and is configured to apply a second application amount of varnish to the recording material per unit area in a case of executing the image forming job for forming the varnish layer on a recording material having a second grammage smaller than the first grammage, the second application amount being larger than the first application amount.

An image forming apparatus includes: a motor which is provided in a housing of the image forming apparatus; a first gear which includes a rotation shaft axially supported by the housing; a first bearing and a second bearing which support the rotation shaft of the first gear and are arranged on one side and the other side of the first gear; a second gear which includes a rotation shaft and meshes with the first gear; a rotating member to which the second gear is attached and which is rotatable with respect to the housing so as to be positioned at a first position at which the first gear and the second gear mesh with each other and at a second position at which the second gear is separated from the first gear; a third bearing and a fourth bearing which support the rotation shaft of the second gear and are arranged on one side and the other side of the second gear; and a holding member which is provided in the housing integrally holds the first bearing and the second bearing, the holding member having a first groove portion which is formed on a movement locus of the third bearing moving by the rotation of the rotating member, into which the third bearing enters when the rotating member moves from the second position to the first position, and which holds the third bearing when the rotating member is positioned at the first position, and the holding member having a second groove portion which is formed on a movement locus of the fourth bearing moving by the rotation of the rotating member, into which the fourth bearing enters when the rotating member moves from the second position to the first position, and which holds the fourth bearing when the rotating member is positioned at the first position.

A lens array unit includes a lens array including a plurality of lenses, a first side plate, and a second side plate, the first side plate and the second side plate being configured to hold the plurality of lenses therebetween, and a frame made of resin and including a first supporting portion and a second supporting portion, the first supporting portion being in contact with an outside surface of the first side plate, the second supporting portion being in contact with an outside surface of the second side plate, the first supporting portion and the second supporting portion being configured to hold the lens array therebetween and support the lens array. The outside surface of the first side plate includes a plurality of first concave portions spaced from each other in an array direction of the lenses and configured to fit with the first supporting portion.

An image-forming apparatus includes, in a body having a predetermined house, an image-reading unit and an image-forming unit that is configured to form an image read by the image-reading unit. A discharge portion is configured to discharge a sheet on which the image was formed onto a discharge tray. An intra-apparatus-discharge space is formed in the body between the image-reading unit and the image-forming unit. The housing includes therein a consumption article mounting portion in which a consumption article used by the image-forming unit is mounted. At least a portion of a surface of the housing at a region of the consumption article mounting portion has a light-transmissive property. When the consumption article is consumed and needs to be replenished, the operator can visually check the region of the consumption article mounting portion in the housing from the outside of the body through the transparent portion.

An image reading apparatus includes a stacking tray, a feeding roller, a restricting member configured to move to a restricting position and a retracted position, a reading sensor, a reversing roller configured to perform a reversing operation, a first conveyance path, a second conveyance, and a controller. The controller is configured to permit the reversing operation if the controller receives an execution instruction of a double-sided reading job on a sheet having a first size, and prohibit the reversing operation if the controller receives an execution instruction of the double-sided reading job on a sheet having a second size smaller than the first size.

An image inspection device includes a processor coupled to a sensor. The processor reads, using the sensor, an image formed on a recording material by an image forming device and creates a read image; causes an analysis to detect an abnormality in the read image and creates an analysis result; and creates a normal image file including the read image in which the abnormality has not been detected based on the analysis result.

An adhesion apparatus includes: an image forming unit configured to form, through an electrophotographic process, an adhesive image of a powder adhesive on a sheet that is conveyed; and a control unit configured to control the image forming unit to use a first pattern in a first conveyance period, and use a second pattern different from the first pattern in a second conveyance period following the first conveyance period, as a formation pattern in an adhering section corresponding to part of a width direction orthogonal to a conveyance direction of the sheet.
