An image forming apparatus which is capable of reading an original, temporarily storing image data in a storage unit, and then transferring the image data to an image forming unit to improve FCOT in forming an image. A memory stores image data output from image reading units. An image forming unit forms an image on a recording medium based on the image data stored in the memory. A first memory output frequency in a first mode in which one side of an original is read and an image is formed on one side of a recording medium is lower than a second memory output frequency in a second mode in which both sides of an original are read and an image is formed both sides of a recording medium.

Image forming apparatus that improves FCOT

An image reading apparatus includes a first unit, a second unit that is pivotable against the first unit, and a controller. The first unit includes a platen, a member, and a movable first reader. The second unit includes an original tray, a conveyance unit that conveys an original from the original tray, a static second reader. The controller determines an opening/closing state of the second unit against the first unit based on read data obtained when the second reader reads the member. The first reader reads the first side of an original conveyed by the conveyance unit and the second reader reads the second side of the original when the original placed on the original tray is read. The first reader reads the first side while moving under the original when the original placed on the platen is read.
