Abstract: A sheet conveyance unit includes a sheet inlet port, an inlet guide, and a guide switching mechanism. The inlet guide has an upper guide and a lower guide below the upper guide. The guide switching mechanism switches a position of the inlet guide between a conveyance position at which the upper guide and the lower guide face each other with a first distance and a separation position at which the upper guide and the lower guide are spaced from each other by a second distance greater than the first distance. To connect the sheet conveyance unit to the sheet discharge unit, the inlet guide is disposed to the separation position before the discharge guide is inserted between the upper guide and the lower guide, and is disposed to the conveyance position after the discharge guide is inserted between the upper guide and the lower guide.

Abstract: A sheet conveying device has a supporting frame that supports a pick-up roller and that moves downward when a sheet is fed, a stepping motor that rotates the pick-up roller and moves the supporting frame downward, and a control portion that starts driving the stepping motor when a job is started and then increases a frequency of the pulse signal to a target frequency. The control portion keeps the frequency of the pulse signal not more than ½ of the target frequency at least until the pick-up roller touches the sheet first.

Abstract: A fixing device includes a fixingmember, a separation member, a movement mechanism, and a pressing member. The fixing member rotates around a rotation axis extended in a rotation axis direction and fixes a toner image on a recording medium. The separation member comes in contact with the fixing member and separates the recording medium from the fixing member. The movement mechanism moves the separation member in the rotation axis direction and within a movement area. The pressing member presses the separation member against the fixing member. A pressing load of the separation member against the fixing member in a case where the separation member is located at a central position of the movement area is lower than a pressing load of the separation member against the fixing member in a case where the separation member is located at both end positions of the movement area.

Abstract: An electrostatic latent image developing toner includes toner particles. Each toner particle includes a toner core containing a binder resin, a shell layer coating a surface of the toner core, and needle-like inorganic particulates. Each shell layer contains a thermosetting resin, and the inorganic particulates are present within the shell layer. The inorganic particulates have: an aspect ratio of 1.25 or more and 2.5 or less; and an average major diameter and an average minor diameter of 300 nm or less.

Abstract: A paper feeder includes a housing, a driving unit, a sheet loading portion, a paper feeding unit, and a lock mechanism. The lock mechanism is located in the housing. The paper feeding unit includes a pickup roller, a second shaft portion, a feed roller, a holder, and a stopper. The stopper is swingably supported in the holder, and is configured to change states between a regulation state and a permission state. The regulation state is a state that regulates entrance of the sheet to be loaded in the sheet loading portion into a side of the feed roller side corresponding to the second position of the holder. The permission state is a state that permits entrance of the sheet into the feed roller side corresponding to the first position of the holder. The lock mechanism locks the holder in the second position at a time of non-paper feeding.

Abstract: A holding member of a sheet feeder includes a locking member engageable with a part of a pinion gear and holds the pinion gear and a sensor member. The holding member is detachably attachable to the sheet storage portion. The pinion gear and a pair of rack members are meshed with the holding member attached to a sheet storage portion. The holding member holds the pinion gear movably in an axial direction of the rotary shaft so that the pinion gear is displaceable between a first position where the rotation of the pinion gear is regulated and a second position where the pinion gear is rotatable. The pinion gear is located at the first position with the holding member detached from the sheet storage portion and located at the second position with the holding member attached to the sheet storage portion.
