IMAGE FORMING APPARATUS, IMAGE FORMATION CONTROL PROGRAM, AND IMAGE FORMATION CONTROL METHOD

摘要

An image forming apparatus includes a control unit that generates a valid region signal corresponding to the length of a paper sheet of a regular size in the conveyance direction thereof, and performs control to form an image on the paper sheet based on the valid region signal, wherein, when an image is formed on a long paper sheet having a longer length than the paper sheet of the regular size, the control unit generates the valid region signal in each channel, performs control for generating the next valid region signal in a period during which the valid region signal is not generated in any of the channels, generates a continuous valid region signal corresponding to the long paper sheet by combining the valid region signals in the channels, and performs control to form an image by reading out image data based on the continuous valid region signal.

1. An image forming apparatus comprising
a control unit configured to generate a valid region signal corresponding to a length of a paper sheet of a regular size in a conveyance direction thereof, and perform control to form an image on the paper sheet by reading out image data based on the valid region signal, wherein, when an image is formed on a long paper sheet having a longer length than the paper sheet of the regular size in the conveyance direction, the control unit generates the valid region signal in each channel of a plurality of channels, performs control for generating the next valid region signal in a period during which the valid region signal is not generated in any of the channels, generates a continuous valid region signal by combining the valid region signals in the channels, the continuous valid region signal being continuous in accordance with the long paper sheet, and performs control to form an image by reading out image data based on the continuous valid region signal.
