According to one embodiment of the present invention, occurrence of a half-latch state when pushing a sheet stacking unit into a sheet feeding apparatus at an angle is prevented. More specifically, inside a sheet feeding apparatus that accommodates and fixes the sheet stacking unit, a latch assembly in which left and right latches and a connecting portion that connects these are configured and that operates integrally is provided. By this, even when one roller of the sheet stacking unit contacts one latch which rides up on the roller in a case where the sheet stacking unit is pushed into the sheet feeding apparatus at an angle, it is possible to hold off on engagement of the latches until the other roller passes the other latch.

An image forming apparatus includes an image forming unit that forms an image on a transfer medium on the basis of image data, a feeder that feeds the transfer medium, and a control unit that manages image data and controls the image forming unit and the feeder. In a case where a base image and an overprint image are printed by the same image forming apparatus, the control unit can manage first image data of the base image and second image data of the overprint image by associating the data with each other, and when a jam of the transfer medium is detected during output of an overprint image, the control unit causes a transfer medium to which the base image is output by the image forming apparatus to be replenished for print instead of a jammed transfer medium removed by jam processing.

A unit moving apparatus includes a unit provided to a main body in such a manner so as to be attached to and pulled out from the main body, a main-body guide portion provided to the main body and configured to guide the unit while restricting rotation of the unit at a time of attaching and pulling out the unit, a pull-in unit configured to apply a pulling force to the unit to pull the unit into the main body, and a unit restriction portion configured to restrict rotation of the unit in such a manner that the units rotates within an angle smaller than an angle to which the main-body guide portion restricts the unit's rotation when a rotation moment is generated by the pulling force of the pull-in unit applied to the unit and a load applied to the unit in a direction opposite to an attachment direction.

A sheet conveyance device includes: a motor; an ON-OFF control unit, which selectively executes an ON control and an OFF control on the motor; a rotation control unit, which selectively executes a first-direction control and a second direction control; a jam detecting unit; an interlock switch; and a setting unit. The first-direction control sets a rotation direction of the motor as a first direction when the motor is rotated by the ON control. The second direction control sets the rotation direction of the motor as a second direction opposite to the first direction when the motor is rotated by the ON control. The setting unit sets the ON-OFF control unit to perform the ON control and sets the rotation control unit to perform the second direction control when the jam is detected by the jam detecting unit and the interlock switch has been turned off.

The image forming apparatus includes an image forming section; a conveyance path to convey a recording medium to the image forming section; a drawer unit including the conveyance path and configured to be pulled out relative to the apparatus; an electrical cable to electrically connect the drawer unit and an interior of the apparatus even when the drawer unit is pulled out from the apparatus; and a cable holder (a first regulating member) to ensure that that the cable is securely prevented from protruding from the drawer unit. According to the present invention, the electric cable is prevented from running off from the drawer unit due to the folding of the cable caused by the regulating member, so that the electric cable is prevented from getting hung up on the parts disposed in the body.

A printing system including: a first printer that forms an image on continuous-form printing paper, and includes a pre-heating unit that preliminarily heats the continuous-form printing paper prior to fixation and a fixing unit that performs the fixation; and a second printer that forms an image on the continuous-form printing paper fed from the first printer. The second printer includes a jam detecting unit that detects, at a detection position upstream of a position where the second printer forms the image on the continuous-form printing paper, and a control unit that controls the jam detecting unit such that the jam detection is not performed for a period of time, over which a deformed portion of the continuous-form printing paper which has been at rest at the pre-heating unit of the first printer passes through the detection position of the jam detecting unit.

An image forming apparatus includes: a cover that is openable and closable. The cover is provided with a lock member, a first biasing portion, a lever member, and a second biasing portion. The lock member is movable between a locking position and an unlocking position. The first biasing portion biases the lock member toward the unlocking position. The lever member is provided to be in contact with the lock member, the lever member being movable between a retaining position for retaining the lock member at the locking position and a retention releasing position for releasing retention of the lock member in a direction intersecting with a moving direction of the lock member. The second biasing portion biases the lever member toward the retaining position.

An image forming apparatus according to one aspect of the present disclosure includes print engine portion, paper sheet detectors, and control portion. Control portion stop paper sheet conveyance, when detecting occurrence of jam. Control portion determines fixing nip position which is position of the fixing nip portion on fixing stop paper sheet, on basis of outputs of paper sheet detectors. When fixing nip position is located at leading end side half of fixing stop paper sheet in paper sheet conveying direction, control portion rotates fixing motor in reverse direction to convey fixing stop paper sheet to upstream side in paper sheet conveying direction. When fixing nip position is located at rear end side half of fixing stop paper sheet in paper sheet conveying direction, control portion rotates fixing motor in a forward direction to convey fixing stop paper sheet toward a downstream side in paper sheet conveying direction.
