Where a pressing force pressing the developing member against the image bearing member is F1, a total number of the carrier particles interposed between the toner particles and the image bearing member is N1, and an adhesion Ft between a carrier particle and a toner particle, measured when the carrier particle is pressed against the toner particle with F1/N1 that is a pressing force per unit carrier particle, and an adhesion Fdr1 between the carrier particle and the image bearing member, measured when the carrier particle is pressed against the image bearing member with F1/N1, satisfy Ft≤Fdr1.

Image forming apparatus

Display screen or portion thereof with graphical user interface

A sheet processing apparatus sandwiches a sheet media in a two-ply sheet in which two sheets are overlaid and bonded together at a portion of the two-ply sheet. The sheet processing apparatus includes a fixing device, a tray, and a roller. The fixing device applies heat and pressure to the two-ply sheet. The tray is disposed downstream from the fixing device in a conveyance direction of the two-ply sheet, to stack the two-ply sheet. The roller conveys the two-ply sheet vertically downward toward the tray after the two-ply sheet passes through the fixing device.

A valve includes a valve housing provided with an inlet port and an outlet port; a valve body to be driven by a drive source; a spring that urges the valve body in a direction opposite a direction of driving by the drive source; and a valve seat formed at an edge of a through-flow passage. The valve body and the valve seat cooperatively form a poppet valve. The valve is configured to control a flow rate in accordance with a movement of the valve body. Flow passages on a downstream side of the poppet valve are provided with increase regions where a flow passage cross-sectional area tends to increase toward the downstream side.

Fluid control valve

A capacity control valve capable of being downsized with the small number of parts is provided. A capacity control valve includes a valve housing provided with a suction port through which a suction fluid of suction pressure Ps passes, and a control port through which a control fluid of control pressure Pc passes, a valve element configured to be driven by a solenoid, a spring that biases the valve element in a direction opposite to a driving direction of the solenoid, and a CS valve formed by a CS valve seatand the valve element and configured to open and close a communication between the control port and the suction port in accordance with a movement of the valve element. The control pressure Pc is controlled by opening and closing the CS valve.

A valve seat is formed at an edge of a through-flow passage. The valve body and the valve seat forms a poppet valve that controls a flow rate in accordance with a movement of the valve body. A flow passage on a downstream side of the poppet valve is provided with a reduction region where a flow passage cross-sectional area tends to decrease toward a downstream side.

A sheet stacker for use in a device including a stacker portion, a fence, and a guide face. The stacker portion includes a stacker face that is inclined at a predetermined angle with respect to a horizontal plane and receives a plurality of sheets ejected from above and stack the plurality of sheets on the stacker face. The fence includes an angled face to contact an end of the plurality of sheets stacked on the stacker face. The angled face rises in a direction in which the plurality of sheets is stacked, with respect to a lower side of the stacker face. The guide face guides the sheet conveyed along the lower side toward an outlet port to a lower end of the outlet port, the outlet port opening in an exterior of the device to remove the sheet to an outside of the device.

Sheet stacker, sheet laminator, image forming apparatus, and image forming system

A sheet separation device separates a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at a bonding portion of the two-ply sheet. The sheet separation device includes a winding roller, a conveyance roller pair, and a separation claw. The winding roller rotates and winds the two-ply sheet. The conveyance roller pair conveys the two-ply sheet toward the winding roller. The separation claw is inserted into a gap between the two sheets at a position between the winding roller and the conveyance roller pair. The separation claw is disposed in a space that is bounded by an imaginary plane and includes the winding roller. The imaginary plane passes through a nip of the conveyance roller pair and a winding start position at which the two-ply sheet starts to be wound around the winding roller.

A sheet processing device includes a conveyor, a rotator, a separator, and control circuitry. The conveyor conveys a two-ply sheet in which two sheets are overlapped and bonded together at a portion of the two-ply sheet. The rotator winds the two-ply sheet. The control circuitry causes the conveyor to convey the two-ply sheet in a winding direction to wind the two-ply sheet around the rotator such that a sagging space is created in the two-ply sheet, and causes the separator to insert into the sagging space to separate the two-ply sheet into two sheets. The control circuitry causes the conveyor to convey the two-ply sheet in a direction opposite the winding direction before an insertion of the separator into the sagging space.
