Disclosed is an image forming apparatus including: a colorimeter; a reader that reads an image formed on a recording medium; and a hardware processor that determines, in accordance with an operation state of the image forming apparatus or a type of a color measurement execution instruction, whether to execute color measurement by the colorimeter or to execute color measurement using the reader.

An image processing apparatus includes a generation unit configured to read an image of a document and to generate an image file based on the read image, a transmission unit configured to transmit the image file generated by the generation unit, a determination unit configured to determine a file name of the image file, and a reception unit configured to receive patient information from an information processing apparatus. The determination unit determines the file name of the image file based on patient information selected by a user from the patient information received by the reception unit.

A document reading device includes: an image capturing member that captures an image of a document; a placement portion that is disposed below the image capturing member and that has a boundary line between multiple surfaces at a position at which the boundary line is covered by the document when the document has a maximum size that the image capturing member is capable of imaging and the document is placed on the placement portion; and a document reading member that reads the document that is placed on the placement portion.

A medium conveying apparatus includes a conveyor to convey a medium, an interface connectable to an external device, and circuitry configured to change whether to allow communication with the external device via the interface or whether to allow supplying power to the external device via the interface based on a state of conveyance by the conveyor.
