摘要： A belt transporting device includes a belt; first and second adjustment members provided at two respective ends of a tension roller in a belt width direction orthogonal to a direction of rotation of the belt, the first and second adjustment members each being movable by receiving a force from the belt; and a link member that interlocks the movement of the first adjustment member and the movement of the second adjustment member. If the belt is laterally shifted in the belt width direction, one of the first and second adjustment members moves by receiving a force from the belt while the other is moved by the link member such that the tension roller is tilted with respect to a driving roller.

摘要： An image forming apparatus includes a main assembly provided with an opening and a tray for placing thereon a cartridge for forming an image, wherein the tray is movable through the opening between an image forming position where the cartridge is used for image formation inside the main assembly and a mounting and demounting position where the cartridge is exposed to an outside of the main assembly and is mountable and demountable. In addition a door opens and closes the opening, and an accommodating member accommodates a sheet on which an image is formed. When the tray is in the mounting and demounting position, the door supports the tray and the accommodating member supports the door.

摘要： A color electrophotographic image forming apparatus includes a movable member for supporting and moving a cartridge. The movable member is movable between (i) a first position in which an electrophotographic photosensitive member carried on the movable member is contacted to a belt member and a latent image can be formed on the electrophotographic photosensitive member and (ii) a second position in which the electrophotographic photosensitive member is spaced from the belt member inside a main assembly frame. The movable member is also movable between the second position and a third position in which the cartridge is mountable and demountable relative to the movable member outside of the main assembly frame.
