摘要： A control method of an image forming apparatus for eliminating waste of sheet when a jam of an original occurs at the time of reading while shortening FCOT (First Copy Output Time) is provided. In the image forming apparatus, when double-sided image reading of the original fed by an ADF and the like is performed, for a first original, before the image reading of the first original is completed, a read image of the first original is started to print (printer output). A second original is not discharged but it is temporarily stopped. Then, if the image reading of the second original is failed, after the second original is replaced and after the image reading is completed, the read image of the second original is started to print (printer output).

摘要： A sheet conveyance apparatus includes a drive transmission mechanism configured to transmit a driving force from a driving source to a rotary conveyance member. The drive transmission mechanism includes a shaft, a first rotary member supported on the shaft and configured to rotate by being driven by the driving source, a second rotary member supported on the shaft and configured to rotate the rotary conveyance member, a drive transmission member provided movably in an axial direction of the shaft, and configured to transmit the driving force between the first rotary member and the second rotary member, and a moving unit configured to move the drive transmission member to a transmission position and a release position. The drive transmission member engages the first and second rotary members with each other at the transmission position, and releases engagement of the first and second rotary members at the release position.

摘要： A drive transmission apparatus includes an engage member that is rotatable in a radially displaced state with respect to a shaft member and an engaged member that is rotatable centering on an axis parallel with the shaft member. The engage member and the engaged member are engaged with and disengaged from each other by relatively moving along an axial direction. The drive transmission apparatus further includes a moving portion which can move the engage member in a direction in which a rotational axis of the engage member approaches an axis of the shaft member in a disengaged condition in which the engage member is disengaged from the engaged member. The moving portion thus regulates offset amount of the engage member in the disengaged condition, so that the engage member and the engaged member reliably engage with each other.

摘要： An image forming apparatus transporting sheets of paper at a predetermined interval and forming an image on the sheets has, as modes for controlling the predetermined interval, a first mode of suspending a next paper feeding operation, for a predetermined time and for every predetermined number of sheets of paper and a second mode of expanding the interval of transportation between the paper feeding operations while continuing the transportation. The image forming apparatus decides whether a predefined first condition for starting control of the interval is satisfied during normal printing, determines a mode of the control in response to a decision that the condition is satisfied, and performs the control in the determined mode. The image forming apparatus calculates power consumption in each mode from the decision that the condition is satisfied to completion of uncompleted printing, and selects a mode in which the power consumption is relatively lower.

摘要： A printing arrangement and printing method are disclosed for two-sided printing on a recording medium, in which intermediate fixing by superheated steam takes place after printing on the first side of the recording medium. Owing to the intermediate fixing, damage to the print image of the first side during subsequent printing on the second side is avoided without the recording medium being impaired by the intermediate fixing.

摘要： An image forming apparatus includes a transfer bias set up section and a developing bias set up section. The transfer bias set up section sets a transfer bias applied to each transfer member so that the transfer bias applied to a transfer member corresponding to a photosensitive member on the most downstream side is greater than a transfer bias applied to a transfer member other than this transfer member. The developing bias set up section sets a developing bias applied to each developing member to a first developing bias in a single-side printing mode, and sets up the developing bias applied to each developing member in formation of an image on a first surface and in formation of another image on a second surface to a second developing bias lower than the first developing bias when the image formed on the second surface is a color image.
