An image forming apparatus includes first, second, and third covers, first and second ducts, and a plurality of image forming units, including first and second image forming units. The second cover is between the first cover and the plurality of image forming units to cover the plurality of image forming units. The first duct is disposed on the second cover to guide air absorbed from outside of the image forming apparatus through an air intake to the first image forming unit. The second duct is disposed on the second cover to guide air absorbed from the outside of the image forming apparatus through the air intake to the second image forming unit. The third cover is attachable to and detachable from the second cover to cover an opening of the second cover. At least part of the first image forming unit is insertable and extractable through the opening.

An image reading apparatus connected to a conveying apparatus to convey a recording medium to which a toner image is fixed includes a conveying unit and a reading unit having a transparent member, a reading sensor, a housing supporting, and a fan. The conveying unit receives the recording medium discharged from the conveying apparatus and conveys the recording medium. The reading unit is positioned downstream of the conveying unit in a conveying direction of the recording medium. The reading sensor read a housing supporting image information about an image on the recording medium through the transparent member. The housing supports the reading sensor and defines, together with the transparent member, an accommodation space configured to accommodate the reading sensor. The fan is positioned in the accommodation space and circulates air in the accommodation space.

Disclosed is a sheet conveying apparatus which includes a rotating member rotatably supported with respect to a frame by a first hinge and a second hinge such that the rotating member is rotatable between a first position where a conveying member for conveying a sheet is covered and a second position where the conveying member is exposed. In the horizontal direction, a position where a first portion of the first hinge is arranged is substantially the same as that of a third portion of the second hinge, and a fourth portion of the second hinge is arranged with respect to the second portion of the first hinge such that a center position of a second scale is located at a position farther from a gravity center of the rotating member than a center position of a first scale.

A cartridge unit includes a first drum cartridge, a first cover member, a stopper, and a first cover erroneous insertion blocking portion. The first cover member is removably attached with the first drum cartridge and configured to be compatible in shape with a first holding portion of a first apparatus body so that the first cover member is guided and held by the first holding portion. The first cover erroneous insertion blocking portion is configured to permit the first cover member to be guided by the first holding portion by a first distance from a first insertion slot portion and to block a second cover member, which is removably attached with a second drum cartridge functionally different from the first drum cartridge, to be guided by the first holding portion in a range exceeding a second distance shorter than the first distance from the first insertion slot portion.

Cartridge unit

A sheet conveyance apparatus, including: a rotatable first rotary member; a second rotary member configured to rotate together with the first rotary member to nip and convey a sheet; a rotary member support unit configured to support the first rotary member in a mountable and removable manner, the rotary member support unit being pivotally movable in a direction intersecting with a conveyance direction of the sheet; and a regulating member configured to regulate pivotal movement of the rotary member support unit so that the first rotary member is fitted into a predetermined position of the rotary member support unit when the first rotary member is mounted.
