An image forming apparatus includes a casing, a connector, and a cover member. The casing including a first and second outer wall portions. The connector is provided inside of the casing and electrically connectable with the external unit. The cover member is attachable to and detachable from the casing. The first outer wall portion includes a first opening configured to expose a connection terminal of the connector. The second outer wall portion includes a second opening configured to expose a component provided inside of the casing. The cover member includes a first cover portion covering the first opening in a state where the cover member is attached to the casing, and a second cover portion formed integrally with the first cover portion and configured to cover the second opening when the cover member is attached to the casing.

Image forming apparatus, image forming system, and external unit

An image forming apparatus includes a casing, an image forming unit, an outer cover, a first inner cover arranged to face an inner side of the outer cover in a closed state, the first inner cover being made of resin, a second inner cover arranged to face the inner side of the outer cover in the closed state, the second inner cover being made of resin, a first fan, and a second fan. The first inner cover includes a first duct configured to guide air taken in from an exterior of the image forming apparatus by rotation of the first fan to the image forming unit. The second inner cover includes a second duct configured to guide air taken in from the exterior of the image forming apparatus by rotation of the second fan to the image forming unit.

Image forming apparatus having first and second inner cover with duct arrangement

An image forming system including: a reading unit configured to read, through a transparent member, an image on a first sheet conveyed by a conveyance unit; an opposed member provided opposite to the reading unit with respect to the transparent member, the first sheet passing through a gap between the opposed member and the transparent member; and at least one processor configured to control, based on the image read by the reading unit, a geometric characteristic of an image to be formed on a second sheet by an image forming portion, and control a changing unit to change the size of the gap to a first size when the thickness of the first sheet is a first thickness, and to a second size larger than the first size when the thickness of the first sheet is a second thickness larger than the first thickness.

Image forming system

An image forming apparatus includes a casing, a fan unit, a support member interposed between the casing and the fan unit, and an elastic member arranged between the support member and the casing. The first duct includes a fixing portion fixed to the casing, the fixing portion being provided on a first side of the fan unit in a first direction. One of the second duct and the support member includes a support projection provided on a second side, opposite to the first side, of the fan unit, and the other one of the second duct and the support member includes a support hole portion defining a support hole. On the second side, the fan unit is supported on the casing via the support member when the support projection is inserted to the support hole and a gap is provided between the support projection and the support hole portion.

Image forming apparatus

An image forming system including: a conveyance unit configured to convey a first sheet on which an image has been formed by an image forming portion; a reading unit including a reading sensor configured to read the first sheet being conveyed by the conveyance unit through a transparent member at a reading position; a guide member configured to cover a reference member on a side opposite to the reading sensor with respect to the transparent member; and a controller configured to perform shading correction on a result of reading the first sheet based on image data obtained by the reading unit reading the reference member through the transparent member, and to control, based on an image subjected to the shading correction, a geometric characteristic of an image to be formed on a second sheet by the image forming portion.

An image reading apparatus including: a conveyance path; a light transmitting member; a first reading unit; a second reading unit; a first roller disposed opposite to the first reading unit; a second roller disposed opposite to the second reading unit; a holding member configured to hold the first roller and the second roller; a plurality of first abutment portions provided on both end portion sides in a width direction of the first roller and forming a gap between the light transmitting member and the first roller by abutting on the light transmitting member; a plurality of second abutment portions provided on both end portion sides in the width direction of the second roller and forming a gap between the light transmitting member and the second roller by abutting on the light transmitting member; and an urging member urges the holding member against the light transmitting member.
