Embodiment Construction
[0028] 1 is a cross-sectional view of the composition of a color digital copier, which is an image forming apparatus having a built-in paper supply device according to an exemplary embodiment of the present invention. This copier is provided with: an image input section 1 that optically reads an image on a document 11 set on an imprint glass 10, and converts the image into electrical image data using a CCD sensor 12; The image data transferred from the image input section 1 forms an image on the recording paper P. As shown in FIG.
[0029] The image forming section 2 forms a toner image on the photosensitive drum 20 based on the image data transferred from the image input section 1, then performs primary image transfer of transferring the toner image to the endless intermediate image transfer belt 3, and then Secondary image transfer for transferring the toner image on the intermediate image transfer belt 3 to the recording paper P is performed to form an image on the recordin...

The invention relates to a paper supply device and a control method, an imaging device, and a computer-readable medium. The paper supply device has: a paper storage section that stores paper; a paper conveyance section that feeds paper from the paper storage section and conveys the paper; a paper separation section that separates the paper conveyed from the paper storage section; a paper thickness measurement section , which measures the thickness of the paper separated by the paper separation section; a paper separation force changing section, which causes the paper separation section to apply one or more of a plurality of paper separation forces to separate the paper; and a control section, which, at The paper separation force changing section is controlled to cause the paper separation section to apply one or more paper separation forces other than the weakest paper separation force among the plurality of paper separation forces during a period beginning when paper starts to be conveyed.
Description
technical field [0001] The present invention relates to a sheet supply device for separating and conveying sheets one at a time and an image forming apparatus equipped with the same. Background technique [0002] In order to form a high-quality image on recording paper in an image forming apparatus using an electrophotography method or an inkjet method, it is necessary to perform an image forming process with appropriate parameters corresponding to the thickness and material of the recording paper, and the like. For example, in order to properly transfer a toner image formed on a photoreceptor to recording paper using an electrophotographic system, it is necessary to set the strength of the transfer bias according to the thickness and material of the recording paper. In the inkjet system, it is necessary to change the inkjet pattern according to the thickness and material of the recording paper, etc. [0003] Generally, recording paper is placed in a paper tray in a stack o...
