In an image forming apparatus, flying of toner from a toner holder towards a counter electrode is controlled by giving a potential to a control grid according to an image signal. Here, a distance between the control grid and the toner holder is set so as to be shorter than a pitch of a gate. The toner passes through a plurality of gates which is a passing section of the toner in the control grid and adheres to a sheet so as to form an image on the sheet. Furthermore, in the image forming apparatus, image signals to be inputted serially from an image reading unit are distributed to odd lines and even lines so as to respectively stored into the odd memory and the even memory. The image signals are stored into the odd memory and at the same time the image signals stored in the even memory are read out.

It is an object of the invention to provide a data transfer apparatus which, when data transfer requests from a plurality of interfaces are to be accepted and processed, can adjust the data transfer so as not to be partially performed on a specific host apparatus. When a plurality of host computers issue a data transfer request, a host I/F which is to be enabled to perform a data transfer is selected from a plurality of host I/Fs on the basis of a priority table. The selected host I/F sends a data transfer enabling signal to the host computer which is connected to the host I/F, to request print data transmission. The host computer which receives the transmission request transmits print data. The print data is transmitted to a printing apparatus via the host I/F which is connected to the host computer, and connecting means. Thereafter, the priority of the host I/F connected to the host computer which is the transmission source of the printed data is lowered to the lowest rank or by a predetermined number of ranks in the priority table.

The present invention provides a system bus control apparatus that effectively utilizes a system bus to the full and realizes efficient data transfer.A system bus control apparatus includes a system bus that is a path of data transferred from a bus master, a bus condition monitoring section that monitors a used condition or unused condition of the system bus, a bus allocating section that allocates a bus width permitted to be transferred by the bus master based on the used condition or unused condition of the system bus monitored by the bus condition monitoring section, when the bus master issues a transfer request, and a bus width variable section that changes the bus width of the data transferred from the bus master in accordance with the allocated bus width.Accordingly, the bus width of the data to be transferred is changed in accordance with the bus width permitted to be used, whereby the transfer request is not brought into a stand-by condition.
