An inclination detecting device includes processing circuitry. The processing circuitry is configured to detect, in image information that is an image of an object imaged by an imaging device at an imaging position where a background member forms a background, a first boundary between the background member and a shadow of the object at detection positions in at least one of main-scanning and sub-scanning directions on an outline of the object; detect a second boundary between the object and the shadow of the object at detection positions in at least one of the main-scanning and sub-scanning directions on the outline of the object in the image information; detect a boundary group including detection results of the second boundary at the detection positions; and detect an inclination of the object in the image information from detection results of the first boundary, the second boundary, and the boundary group.

An image reading apparatus includes: a transmitting glass; and a step member that is located upstream of a reading position, at which an image of a conveyed document is read by a reading unit via a transmitting glass, in a conveying direction of the document, and has a document guiding surface at a position away from a surface of a transmitting glass by a prescribed distance and forms a step between the document guiding surface and the transmitting glass. The step member is provided with a protrusion protruding downstream in the conveying direction of the document to form space between the transmitting glass and a downstream part of the step member in the conveying direction of the document.

According to an embodiment, an ADF that feeds and conveys original document sheets one sheet by one sheet from a tray unit to a read position on a document glass by motive power from a driving motor includes: an opening/closing unit operable to open and close relative to the document glass; an open/close detection sensor that detects an open/closed state of the opening/closing unit; a first interlock switch, which is arranged between a power source and the driving motor, that is on when the opening/closing unit is closed, and vice versa; and a control circuit that determines the open/closed state of the opening/closing unit based on detection outputs of the first interlock switch and the open/close detection sensor. The control circuit determines that the opening/closing unit is in the closed state when the first interlock switch is on and the open/close detection sensor is detecting the closed state.
