Title:
画像形成装置
Document Type and Number:
Japanese Patent JP6794230
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To shorten an FPOT while keeping image quality at image formation without adding a new structure.SOLUTION: A control device 200 calculates a distance enabling acceleration until paper reaches a transfer roller 106, on the basis of a timing at which a carrying motor 301 feeds paper so as to enable the paper to reach a fixing unit 130 when the fixing unit 130 rises to a target temperature, a timing at which a charging roller 123 starts charging and the carrying motor 301 can feed paper so as to enable a toner image on a photosensitive drum 122 and the paper to reach a transfer roller 106, a timing at which a scanner unit 108 starts the light expose of the photosensitive drum 122 and the carrying motor 301 can feed paper so as to enable the toner image on the photosensitive drum 122 and the paper to reach a transfer roller 106, and a paper feeding start timing at which paper carrying is started. The control device 200 controls the carrying motor 301 so as to carry the paper at a carrying speed Vor a carrying speed V, according to the calculated distance enabling acceleration.SELECTED DRAWING: Figure 4
