ABSTRACT:
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.
