An image forming apparatus includes an image bearer, a nip forming device, a contact-and-separation device, a thickness information retrieving device, and a controller. The contact-and-separation device moves the image bearer and the nip forming device to contact and separate from each other. The controller controls the contact-and-separation device based on information on a thickness of a recording medium obtained by the thickness information retrieving device such that in a case in which a thickness of a preceding recording medium and a thickness of a successive recording medium are different in continuous printing in which a plurality of recording media is printed out continuously, the contact-and-separation device adjusts a space between the image bearer and the nip forming device when the preceding recording medium exits the transfer nip to a preset size corresponding to the thickness of the successive recording medium that enters the transfer nip.

An image forming apparatus includes an apparatus body, a plurality of image bearers, an endless belt, a contact and separation mechanism to generate a first trajectory and a second trajectory of the endless belt, a sensor to detect an object on a surface of the endless belt, and a positioning mechanism to enable the sensor to detect the object in the first trajectory and the second trajectory of the endless belt. The positioning mechanism includes a stay to support the sensor, a first bracket, a second bracket, a first positioning portion attached to the apparatus body to position the sensor in a direction of rotation of the first bracket and the second bracket at a time of the first trajectory, and a second positioning portion attached to the second bracket to position the sensor in the direction of rotation of the first bracket at a time of the second trajectory.

A sheet conveyance device includes a conveyor configured to convey a sheet in a sheet conveyance path and a discharger disposed at an intermediate position in the sheet conveyance path. The conveyor is configured to contact the sheet in a contact range within and narrower than a passage range where the sheet passes through the sheet conveyance path in a width direction of the sheet. The discharger is disposed close to the sheet that the conveyor is conveying in the sheet conveyance path, in a range different from the contact range and configured to remove static electricity from the sheet that the conveyor is conveying in the sheet conveyance path.

A system provides an image displaying technique that provides stable high contrast even in an area having high brightness. Based on information about an average brightness level of a digital luminance signal, black-correction processing which decreases a brightness level by offsetting the brightness level to the minus side, and increase processing which increases a contrast gain within a dynamic range, are performed for an analog luminance signal or a digital luminance signal, enabling improvement in contrast even where brightness is intense.

An image forming apparatus includes an image bearer having an image bearing face to bear an image thereon; a transferer disposed opposing the image bearer, to transfer the image from the image bearing face onto a recording medium at a transfer section between the transferer and the image bearer; a first guide disposed upstream from the transfer section in a direction of delivery of the recording medium, to guide the recording medium to the transfer section; and a second guide upstream from the first guide and spaced away from the first guide, to guide the recording medium to the transfer section. Each of the first guide and the second guide extends in a lateral direction perpendicular to the direction of delivery. A leading end of the second guide in the direction of delivery is inclined from one end to the other end of the second guide in the lateral direction.

A transfer unit detachably mountable relative to an image forming apparatus includes a plurality of rotational supports, an endless-looped belt disposed opposite to an image bearer and movably supported by the plurality of rotational support to contact the image bearer to form a transfer portion at which the toner image is transferred, a contact-and-separation device to move the belt to contact and separate from the image bearer, a base to support the plurality of rotational supports, a belt pressing member disposed facing the belt and detachably mountable relative to the base to contact an end portion of the belt, and a first stopper to prevent the belt pressing member from separating from the base while the belt is in contact with the image bearer by the contact-and-separation device and to allow the belt pressing member to separate from the base while the belt is separated from the image bearer.

An image forming apparatus includes a scanning optical device which performs scanning on a photosensitive drum with laser light. The scanning optical device includes a polygon motor unit, an emergence unit and a projecting unit. The polygon motor unit includes a polygon mirror which performs the scanning on the photosensitive drum with the laser light emitted from a light source. The laser light emerges from the emergence unit so that the photosensitive drum is irradiated with the laser light. The projecting unit projects to a first side where the photosensitive drum is disposed from a partition wall. The polygon motor unit is disposed in the projecting unit. The emergence unit is disposed on a second side separated from the first side by the partition wall. A gap is provided between the partition wall and the scanning optical device.

A scanning optical device that scans a photoreceptor with laser light includes a light source, a light outputting section, and a projection. The laser light from the light source is output through the light outputting section so that the photoreceptor is irradiated with the laser light. The projection projects through a partition wall toward the photoreceptor. The light outputting section is disposed in a position separated from the photoreceptor by the partition wall. The projection contains a polygon motor that rotates a polygon mirror to reflect the laser light.
