摘要： An armored unit includes a side cover and a guide member. When sheet jam operation is carried out, a fixing unit is pulled out with the armored unit, and then is pushed to the rear side. This operation unlocks the lock member provided in the guide member, and a shoulder screw moves in a guide hole. Thus, the fixing unit is moved from the pulled out position toward the rear side and toward the main body of image forming device to be shifted to a receding position. On this account, it is possible to provide an image forming device ensuring sufficient space for removing a jammed sheet by hand with a small opening space.
摘要翻译：铠装单元包括侧盖和引导构件。当进行卡纸操作时，用铠装单元拉出固定单元，然后将其推向后侧。该操作解除了设置在引导构件中的锁定构件，并且肩部螺钉在引导孔中移动。因此，定影单元从拉出位置朝向图像形成装置的主体朝向后侧移动并且朝向图像形成装置的主体移动以转移到后退位置。因此，可以提供一种图像形成装置，确保用小的开放空间用手去除卡住的片材的足够的空间。

摘要： In an image forming apparatus, a computing unit computes phase shift amounts A(i) for every correction relative phase angle θ(j) based on an amplitude B of a reference compressional wave αa, an amplitude C(i) of a detection compressional wave α(i), and a relative phase angle φ(i). A setting unit specifies the phase shift amounts A(i), and sets a correction relative phase angle θ(j) corresponding to the specified phase shift amounts A(i). A correction unit corrects, based on the correction relative phase angle θ(j) set by the setting unit, a relative phase shift between a periodic variation in the circumferential speed of a first image bearing member and a periodic variation in the circumferential speed of a second group image bearing member by operationally controlling at least one of first and second drive units.

摘要： Multiple photoconductive drums on which images with different color components are formed respectively are rotated using individual motors, multiple adjustment images are formed at a predetermined interval along the cycle length of one rotation of each photoconductive drum, the reference phases for the rotation of the respective photoconductive drums are determined based on the maximum portions of the divergences between the predetermined interval and the detection interval of each adjustment image, and the individual motors are controlled so that the respective reference phases determined are aligned. The image forming region corresponding to the cycle length of one rotation of the photoconductive drum is divided into four or more even-numbered regions, the divergence amount of each region is calculated, and the maximum portions of the divergences are determined based on the difference between the divergence amounts of the divided regions being away from each other by a half cycle length.

摘要： To provide an image forming apparatus which can prevent malfunction of the open/close control of a shutter due to erroneous detection of the toner on the transfer belt when the opening and closing of the shutter is detected from the output from an optical sensor. The separation/contact assembly for moving a cleaning member into and out of contact includes an arm rotationally supported on a pivot, an abutment part fixed to the body frame so as to limit the rotation of the arm and a spring for pressing the arm in the clockwise direction. The cleaning member is attached at the distal end of the arm. The cleaning member cleans the transfer belt surface when the shutter is closed, so that the cleaned transfer belt surface can be always detected when the shutter is open.

摘要： An image forming apparatus in which a plurality of color component images of different colors, which include a reference color (e.g. black) serving as a reference and adjustment colors (e.g. cyan, magenta and yellow) to be adjusted, are formed on respective photosensitive drums and then transferred to a transfer belt. Respective positions of the color component images transferred to the transfer belt are detected by a CCD. Timing adjustment can be performed so that the difference between the detected position of each of the color component images and a prescribed position is not more than a predetermined value, based on the reference color image as the reference. In this case, the color component images are formed on the corresponding photosensitive drums with the same timing by utilizing a single polygon mirror.
