Image forming apparatus that improves printing speed and recording medium

摘要

An image forming apparatus according to one aspect of the disclosure includes a printing mechanism, a drawing data creating circuit, a medium supply circuit, and a charging circuit. The medium supply circuit performs: a primary supply supplying the printing medium to a specific position; and a secondary supply supplying the printing medium from the specific position to the printing mechanism. When the band-used color fixed as color by the drawing data creating circuit exists, the medium supply circuit starts the primary supply prior to completion of creating all the bands of the drawing data by the drawing data creating circuit. When the band-used color fixed as color by the drawing data creating circuit exists, the charging circuit performs the charging process in a case where the color for use is color, in starting the primary supply.

主权项

1. An image forming apparatus comprising:
a printing mechanism that prints on a printing medium; a drawing data creating circuit that creates drawing data for each band in order, the drawing data causing the printing mechanism to print; a medium supply circuit that supplies the printing medium to the printing mechanism; and a charging circuit that performs a charging process for printing, wherein the medium supply circuit performs:
a primary supply supplying the printing medium to a specific position; anda secondary supply supplying the printing medium from the specific position to the printing mechanism, wherein the drawing data creating circuit fixes a band-used color used for each band in printing, performed based on the drawing data by the printing mechanism, to one of monochrome and color, the drawing data creating circuit fixing a color for use in printing, performed based on the drawing data by the printing mechanism, to one of monochrome and color, wherein when the band-used color fixed as color by the drawing data creating circuit exists, the medium supply circuit starts the primary supply prior to completion of creating all the bands of the drawing data by the drawing data creating circuit, and wherein when the band-used color fixed as color by the drawing data creating circuit exists, the charging circuit performs the charging process in a case where the color for use is color, in starting the primary supply.
