An input device that is mountable on an image forming apparatus includes a plurality of numerical keys arranged as hardware keys, a connector provided in a casing of the input device and configured to electrically connect the image forming apparatus and the input device, and a USB port provided in the casing and configured to USB-connect external equipment, which is different from the image forming apparatus, to the input device. As viewed in an up-down direction that the numerical keys are pressed, the USB port is provided on a front side surface of the casing.

An image forming apparatus includes a photosensitive member, a charging member, an electrostatic image forming portion, a developing member, a transfer member, a transfer voltage source, a brush member, a brush voltage source, and a controller capable of executing a cleaning operation. The controller carries out control so that the cleaning operation includes a first operation in which a potential difference is formed between the transfer member and the photosensitive member so that toner charged to a normal charge polarity is moved from the transfer member toward the photosensitive member, and a second operation in which a potential difference is formed between the brush member and the photosensitive member so that the toner charged to the normal charge polarity is moved from the photosensitive member toward the brush member.

A first guide member guides a sheet from a sending roller pair to a discharge port. A second guide member is disposed above the first guide member such that an upstream end of the second guide member in a sheet discharge direction overlaps the first guide member, and forms an upper partition of a discharge path in an area extending from a position above an end of the first guide member to a position of a discharge roller pair. The second guide member guides the sheet to the discharge roller pair. A cooling fan blows air from below the discharge path toward a lower surface of the second guide member. The lower surface of the second guide member is formed convexly curved upward when viewed in a width direction intersecting the sheet discharge direction. The lower surface of the second guide member guides air toward the first guide member.

A printing system includes a printing mechanism. The printing mechanism is configured to perform printing. The printing system stores a plurality of print jobs in a storage, and receives selections of two or more print jobs to be executed as two or more target jobs from among the plurality of print jobs stored in the storage. The printing system determines a total fee to be charged for executing the two or more target jobs, and performs a settlement related process related to settlement of the determined total fee. The printing system executes the two or more target jobs to print images by using the printing mechanism in response to completion of settlement of the total fee.

A printing system includes: a printer including a controller; and a contract processing server. The controller is configured to perform: determining, in response to receiving from an external device a print job including print data representing an image, whether authority information indicating an authority to print the image has been issued; and transmitting, in response to determining that the authority information has been issued, to the contract processing server an inquiry for determining whether the authority information is valid. The contract processing server is configured to perform: transmitting, in response to receiving the inquiry, a response to the controller. The controller is configured to further perform: determining, in response to receiving the response, whether the authority information is valid on the basis of the received response; and printing, in response to determining that the authority information is valid, the image on a print medium by controlling the printer.

An MFP 1 includes an image forming unit 4 which forms an image on a sheet S1, a USB interface 12 which is to be connected to a PC 101 via a USB and receives a preceding command described in accordance with a control transfer protocol that is a transfer scheme of USB connection, and a CPU 91 which executes a preparation operation of the image forming unit 4, in response to receiving the preceding command by the USB interface 12. The preceding command is described to instruct the preparation operation of the image forming unit 4.

An image forming apparatus includes a rotatable image bearing member, a developing unit to develop an electrostatic latent image at a developing portion, a transfer unit to transfer a developer image to a recording member at a transfer portion; and a brush provided with a plurality of fibers contacting the image bearing member at downstream of the transfer portion and upstream of the developing portion in a rotational direction of the image bearing member. An average contacting pressure of the brush per one fiber to the image bearing member is smaller than a depositing force of the developer not transferred to the recording member to the image bearing member. As the brush in a state of not in contact with the image bearing member is viewed from a free end side of the fibers, an average number of the fibers included in a circumference of a diameter of 100 μm is more than one.

An image forming apparatus includes a rotatable photosensitive member, a charging member, a developing device, a transfer member, a brush, a driving source and a control portion. The control portion controls the driving source to execute an image forming process in which image formation to the recording material is executed and a non-image-forming process in which the photosensitive member is driven to rotate other than the image forming process. The non-image-forming process between a first recording material and a second recording material to which the image formation is executed following the first recording material is defined as a first non-image-forming process, and the non-image-forming process between the second recording material and a third recording material is defined as a second non-image-forming process. The control portion determines a time of the second non-image-forming process based on a history information correlating with a usage amount of the photosensitive member and a time of the first non-image-forming process.
