Problems solved by technology

This is because, in the case of a monochrome image job, if the state of forming a color image is maintained, the three (YMC color) photoreceptors that should not be used are worn by the intermediate transfer belt, resulting in material consumption.

Embodiment Construction

[0086] Hereinafter, embodiments of the present invention will be described based on the drawings, but the present invention is not limited to the following embodiments.

[0087] figure 1 It is a configuration diagram schematically showing an image forming apparatus according to an embodiment of the present invention. The image forming apparatus 1 includes a continuous paper supply device 1A, an image forming apparatus main body 1B, and a continuous paper winding device 1C.

[0088] The continuous paper supply device 1A stores continuous long continuous paper P and supplies the continuous paper P to the image forming apparatus main body 1B according to an instruction from the image forming apparatus main body 1B. The continuous paper P is, for example, roll paper wound around a shaft. In addition, the continuous paper P may be a so-called fanfold paper. In addition, the continuous paper P may have perforations for easy cutting later. Such a continuous paper supply device 1A...

Abstract

The present invention provides an image forming apparatus capable of appropriately switching between a color image forming state and a monochrome image forming state. An image forming device (1) is a device that continuously forms images corresponding to jobs in a conveyance direction of continuous long continuous paper P, and includes: an LD unit (21) that forms images corresponding to jobs on the continuous paper P; an interval setting section (32a), which sets job intervals of images corresponding to jobs continuously formed by the LD section (21) based on an operation from a user; a printer control section (22), which forms switching between two states of a state of a color image and a state of forming a monochrome image; According to the comparison result of the paper conveying distance corresponding to the switching time required for the switching between the two states, it is judged whether to execute the switching between the two states.

Description

technical field [0001] The present invention relates to an image forming apparatus. Background technique [0002] At present, in image forming apparatuses that form images on continuous paper such as roll paper, it is proposed to judge whether to give blanks between jobs according to the patterns of the first job and the second job, so as to reduce the generation of wasteful paper caused by blanks (for example, refer to Patent No. Literature 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2015-212051 [0006] The problem to be solved by the invention [0007] Here, in an image forming apparatus that forms images on continuous paper such as roll paper disclosed in Patent Document 1, it is desirable to respond to job intervals that require shortening the distance between the final image of a job and the first image of the next job. Continuous printing is performed at the job interval specified by the us...
