An image forming apparatus has a sheet feed portion, a conveying portion, a control portion, a first sensor having the detection position at a first position in the sheet conveying passage, and a second sensor having the detection position at a second position downstream of the first position in the sheet conveying direction. The control portion performs first sensing to sense whether the sheet's rear end has passed the first position within a first time of the start of the feeding and second sensing to sense whether the sheet's rear end has passed the second position within a second time of the start of the feeding, Even if the control portion is unable to sense passage of the sheet's rear end in the first sensing, when it senses passage of the sheet's rear end in the second sensing, it makes the conveying portion continue feeding the sheet.

A guide structure includes a first guide member that guides a recording medium from a fixing unit to a transport roller unit, the fixing unit fixing an image formed on the recording medium to the recording medium by heating the recording medium that is transported, the transport roller unit transporting the recording medium; and a second guide member that comes into contact with the recording medium to which the image has been fixed by the fixing unit and guides the recording medium to the transport roller unit, the second guide member being disposed downstream of the first guide member in a transporting direction in which the recording medium is transported and being made of a material having a thermal conductivity higher than a thermal conductivity of a material of the first guide member.

A sheet conveyance apparatus includes a shaft portion, a roller member, and a guide member. The roller member includes a hole portion with an opening through which the shaft portion is fitted with the hole portion. At least a part of the guide member is located upstream of an end of the shaft portion in an attaching direction of the roller member. The end of the shaft portion is located inside the opening of the hole portion when viewed in the attaching direction in a state where an outer circumferential surface of the roller member is in contact with the guide member at a position upstream of the end of the shaft portion in the attaching direction.

A sheet conveyance apparatus includes a conveyance portion including a rotary member and an opposing member and configured to convey a sheet in a conveyance nip, an abutting member configured to abut a surface of the rotary member, and a support portion, wherein the support portion supports the rotary member between a first position and a second position with respect to the abutting member, wherein when the sheet is not passing through the conveyance nip, the rotary member is positioned at the first position, and when the sheet is passing through the conveyance nip, the rotary member is positioned at the second position which is more separated from the opposing member than the first position by a thickness of the sheet, and wherein the abutting member abuts the rotary member regardless of which of the first position and the second position the rotary member is positioned at.

An image forming apparatus is configured such that in a case where images are to be formed on a first surface of a preceding sheet, on a first surface of a succeeding sheet fed to the first conveyance path succeeding to the preceding sheet and on a second surface of the preceding sheet, a first conveyance member is stopped without reversing the preceding sheet to a second conveyance path in a case where the image has been formed on the first surface of the preceding sheet and permission of preparing the image to be formed on the first surface of the succeeding sheet is not issued yet, and the first conveyance member restarts conveyance of the preceding sheet to the second conveyance path based on timing when an image forming unit starts preparing the image to be formed on the first surface of the succeeding sheet.

A driving device includes: a first motor that transmits power to a rotation shaft of a conveyance roller for conveying a paper sheet; a second motor that transmits power to the rotation shaft of the conveyance roller; and a motor controller that controls rotational speeds of the first and second motors by changing a control value, wherein the motor controller controls the control value of the first motor at multiple steps at a time of acceleration or deceleration and changes the control value of the second motor according to a change range of the control value of the first motor in synchronization with a timing when the control value of the first motor is changed.

A transfer unit that transfers a developing agent image formed with a developing agent, includes a belt; and a rotational body that stretches the belt. The rotational body includes a shaft body, and a surface layer provided on an outer side of the shaft body in radial directions. Surface roughness of an outer peripheral surface of the surface layer is greater than a volume mean particle diameter of the developing agent.

An image forming apparatus includes a conveyance guide, a measurement unit, an opposing member, and a holding member. The conveyance guide has an opening and forms a conveyance path through which a sheet with an image formed on the sheet is conveyed. The measurement unit measures, through the opening, a color of the image on the sheet being conveyed through the conveyance path. The opposing member opposes the measurement unit at a measurement position of the measurement unit. The holding member holds the opposing member so that the opposing member is movable between a first position where the opposing member presses the sheet against the opening and a second position where the opposing member is separated from the opening as compared with the first position. The holding member includes an abutment portion that abuts against the conveyance guide in a state where the opposing member is at the first position.

A fixing device includes: a heating section that heats in a non-contact manner a front surface of a recording medium; a feeding section that feeds the recording medium while causing the front surface to be opposed to the heating section; and a maintaining section that, in order to enable the recording medium to be fed by the feeding section while a rear surface that is opposite to the front surface, and that is in an image region where an unfixed-image is formed on the front surface is in a non-contact state, maintains the non-contact state.

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.
