A sheet processing apparatus includes a conveyance unit configured to convey a sheet, a stacking portion on which the sheet conveyed by the conveyance unit is stacked, a first regulation member configured to regulate a position of an edge portion, in a conveyance direction, of the sheet stacked on the stacking portion, a second regulation member configured to regulate a position of an edge portion, in a width direction orthogonal to the conveyance direction, of the sheet stacked on the stacking portion, a binding unit supported movably in the conveyance direction and configured to perform a binding process of binding the sheet stacked on the stacking portion, and a moving unit configured to move the second regulation member in the conveyance direction accompanied with a movement, in the conveyance direction, of the binding unit.

A transfer device includes: a transfer drum that has a groove-like recess extending in an axial direction in an outer circumferential portion thereof, rotates about an axis thereof, and comes into contact with a medium being transported at a portion thereof on an upstream side of the recess in a rotation direction; a nip member, the nip member and the transfer drum forming therebetween a nip part where the medium is nipped; an application member that applies a voltage to the nip part where the medium is nipped, so that an image is transferred to the medium; and a contact mechanism that causes the nip member to come into contact only with a portion on the upstream side of the recess in the transfer drum in the rotation direction at a transfer-start time when the transfer of the image to the medium starts.

A flexible touch panel including a flexible substrate bent in a first direction, and a touch sensor unit disposed on the flexible substrate, the touch sensor unit including a bridge extending in a second direction intersecting the first direction.

A relationship 150≦Rs (Ω)/Rm (Ω)≦4000 is established in an environment of a temperature of 15° C. and a humidity of 10% in a case where a surface resistance of a transfer roller is Rs (Ω) when a current is fed between a pair of electrodes facing each other in an axial direction of the transfer roller and arranged on a surface of the transfer roller with an interval of 5 mm therebetween, the electrodes having a width of 20 mm in a circumferential direction of the transfer roller in a state of being arranged on the transfer roller, and in a case where a combined resistance of a first layer and a second layer is Rm (Ω) when the current is fed from a core portion to an outer peripheral surface of the second layer.

A rotating member control device that controls a first rotating member and a second rotating member to convey a sheet includes a processor configured to execute a program to implement processes of controlling the first rotating member and the second rotating member to come into contact or be separated from each other and acquiring a value that corresponds to or is proportional to a driving torque of a first driving unit that rotationally drives the first rotating member. The processor acquires the value upon separation when the first rotating member and the second rotating member are separated from each other and upon conveyance when the sheet is held between and conveyed by the first rotating member and the second rotating member. The processor further sets a rotational speed of the second rotating member such that the value acquired upon separation and the value acquired upon conveyance become equal.

A sheet conveyance device includes a registration roller pair including a first roller and a second roller, configured to form a nip by the first roller and the second roller, and configured to correct a skew of a sheet conveyed thereto by allowing the sheet to abut the nip. The first roller includes an outer peripheral surface with a groove portion, the groove portion being formed in a region in which a corner portion of a sheet abuts the outer peripheral surface, and causing a part of the outer peripheral surface to be concave and another part of the outer peripheral surface to be convex in an axial direction.

A belt conveyance apparatus includes a plurality of support rollers, an endless belt, a regulation portion configured to regulate a shift of the endless belt in a width direction, a regulation receiving member configured to contact the regulation portion to receive a regulation force by the regulation portion, and support members disposed on an upstream side, in a conveyance direction of the endless belt, of the support rollers provided with the regulation portion to oppose each other on an inner peripheral surface side and an outer peripheral surface side of the end portion side of the endless belt in the width direction, and configured to regulate a position of the regulation receiving member when the regulation receiving member enters a contact portion with the regulation portion.

An image forming device continuously forming an image according to a job in a conveying direction of along continuous paper includes: an image formation section forming the image according to the job on the continuous paper; an interval setting section setting a job interval of the image according to the job, which is continuously formed by the image formation section, on the basis of an operation from a user; an image forming process switching section switching two states of a state where the image formation section forms a color image and a state where the image formation section forms a monochromic image; and a switching determination section determining whether or not the two states are switched on the basis of a comparison result between the job interval set by the interval setting section and a paper conveying distance according to a switching time required for switching the two states.

To provide a rotating shaft with which flexibility of forming a bend is increased, and the strength is increased while reducing the amount of material.

A V-shaped rotating shaft formed by bending sheet metal. An angle formed on an inner side of a bent portion is less than 90°.

An image formation device includes: a registration roller pair configured to shift sheet in a second direction perpendicular to a first direction of a sheet feeding direction while holding the sheet; a feeding section provided upstream of the registration roller pair in the first direction and including a feeding belt configured to convey the sheet to the registration roller pair; a first air adjustment section configured to perform air suction or blowing for the sheet conveyed by the feeding belt; and a control section configured to switch between a first operation of controlling, when the sheet is conveyed by the feeding belt, the first air adjustment section to suck the sheet with air and a second operation of controlling, when the sheet is swung by the registration roller pair, the first air adjustment section to blow air on the sheet.
