摘要： An image forming apparatus includes a fixing unit, a first guiding unit having a first surface forming a first feeding passage, and a second guiding unit forming a second feeding passage. The second guiding unit includes a first member made of metal and having a first guiding surface on which a leading end of a sheet is guided in a first section including an upstream end portion of the second feeding passage with respect to a sheet feeding direction, and includes a second member made of a resin material and having a second guiding surface on which the sheet is guided in a second section downstream of the first section in the second feeding passage with respect to the sheet feeding direction. The first guiding surface is spaced from a first phantom contact surface extending from an end portion of the first surface and contacting the second guiding surface.

摘要： An external cooling device 101 is connectable to an image forming apparatus 100. The external cooling device 101 improves cooling power of a recording material S after toner image fixation. In this case, even when a heating amount of the fixing device 11 is increased, a temperature of the recording material S stacked on a stacking unit 60 can be lowered to not more than a predetermined temperature at which sticking does not occur. Further, the number of sheets stackable on said stacking unit 60 can be increased. By this, a user is capable of adjusting glossiness without concern for the sticking of the recording materials S on the stacking unit 60. Further, the user is not required to frequently carry out the recording material S of the stacking unit 60. That is, it is possible to provide an image forming system 1X capable of flexibly meeting the recording materials S of various kinds.

摘要： An image forming apparatus includes an image forming portion configured to form an image on a sheet; a pair of conveyance rotary members arranged downstream of the image forming portion in a sheet conveyance direction and configured to convey the sheet, on which the image is formed, by a conveyance nip; and a guide portion configured to guide the sheet to the conveyance. The guide portion includes a first guide member formed into a sheet shape and having a first stiffness and an abutment surface configured to abut the sheet and a second guide member formed into a sheet shape and having a second stiffness higher than the first stiffness and arranged on a side opposite to the abutment surface of the first guide member, wherein a downstream edge of the first guide member is closer to the conveyance nip than a downstream edge of the second guide member.

摘要： The present disclosure provides a drive transmission apparatus including a swing gear mechanism and capable of reducing the workload during assembly and improving efficiency of the assembly operation. A first swing gear, which transmits rotation of a first input gear that is driven by a driving force, is held by a first swing member. The first swing member includes a first engagement portion engaging with a supporting portion, and swings around an axis of the first input gear. The first engagement portion is formed so as to be attached to and detached from the supporting portion if the first swing member is moved in a radial direction with respect to the axis.

摘要： An image forming apparatus includes an image forming portion, an oblique movement correcting portion including a first registration roller pair and a first moving portion, a reversing portion, and a re-feeding portion. The reversing portion includes a reversing roller pair and a second moving portion. The re-feeding portion includes a second registration roller pair. When an image is formed on a second surface of a sheet opposite from a first surface of the sheet, a side end position of the sheet is corrected by the second moving portion and oblique movement of the sheet is corrected, and then the side end position of the sheet is corrected again by the first moving means and the sheet is fed to the image forming portion.
