An image reading apparatus according to the present disclosure includes a platen glass, an image reader, and an output interface. An original is placed on the platen glass. The image reader is configured to read an image of the original on the platen glass. The image reader includes at least one sensor configured to detect a quantity of light for each of a plurality of regions on the platen glass. The output interface is configured to output information which identifies one or more regions of the plurality of regions in which the quantity of light detected therefrom exceeds a given value.

Image reading apparatus and method for controlling the same

There is provided a cleaning device capable of maintaining a sufficient cleaning effect by preventing creep deformation of a cleaning member. The cleaning device of the present invention for cleaning a transfer body in an image forming apparatus includes a first cleaning member whose top end is brought into pressure contact with the transfer body, and a second cleaning member which is placed downstream from the first cleaning member with respect to a moving direction of the transfer body and whose top end is brought into pressure contact with the transfer body, wherein the second cleaning member is provided rotatably with respect to the first cleaning member.

Creep resistant cleaning device and image forming device having the same

There is provided a development cartridge capable of switching development colors in a plurality of development cartridges without using development rack. A development cartridge of the present invention has a part of a drive member for switching development colors.

Development cartridge, development device, and image formation apparatus

An image forming apparatus according to the invention includes, in an apparatus body, an image carrier on which an electrostatic latent image is formed; and a rotary-type development unit being rotatable about an axis thereof and having a plurality of developing devices, which are used for developing the latent images formed on the image carrier. The rotary-type development unit is formed with cavities at an outer periphery thereof for receiving gas. The rotary-type development unit is rotated for sequentially advancing the gas in the cavities whereby the gas in the apparatus body is discharged out of the apparatus body.
