An image forming apparatus includes processing circuitry. The processing circuitry receives a timing selected for re-forming an image and re-forms the image determined to be defective based on information about the image formed on a first conveyance medium, on a second conveyance medium at the selected timing.

An example jam removal structure can include a transporting roller transporting a print medium along a transporting path, an Inner-side guide, and first and second guides facing the inner-side guide to form the transporting path and located in an upstream side and a downstream side of the transporting roller based on a transport direction of the print medium to be rotatable to an open position opening the transporting path and a path formation position forming the transporting path. The example jam removal structure can include an operating lever connected to each of the first and second guides by first and second connecting members to switch the first and second guides to the open position or the path formation position and an elastic member applying an elastic force to the first and second guides in a direction rotating toward the path formation position.

An image forming apparatus includes a processor. The processor is configured to stop a print job under execution in response to an occurrence of an abnormality preventing the print job from continuing, set the stopped print job to a skip state, and restart the print job set to the skip state in response to a restart instruction by a user associated with the print job and not by a second user different from the user associated with the print job.

An image forming apparatus includes a latent image bearer, a toner image forming unit, an intermediate transfer member, a primary transfer member, a secondary transfer member, a switching unit, and control circuitry. The toner image forming unit forms toner images on the latent image bearer. The primary transfer member transfers the toner images on the latent image bearer onto the intermediate transfer member. The secondary transfer member transfers the toner images on the intermediate transfer member onto recording materials. The switching unit switches a position of one of the secondary transfer member and the intermediate transfer member between a first and a second position. The control circuitry controls at least one of a first and a second operation. The control circuitry changes at least one of the first and the second operation when the toner images satisfy a specified abnormal image reduction condition at a first and a second timing.

According to one embodiment, an image forming apparatus includes a plurality of parts, an acquisition unit, and a control unit. The plurality of parts are used in the image forming process and are replaced according to the degree of use. The acquisition unit acquires, for each of the parts, use-related information that is information indicating the degree of use of the plurality of parts. The control unit determines the replacement timing of the part using the plurality of pieces of use-related information acquired by the acquisition unit and the determination condition regarding the replacement timing of the part.

Disclosed is an image forming system including: an image forming apparatus; and an operation unit communicating wirelessly with the image forming apparatus. The operation unit includes a touch panel display, a first memory temporality storing a first screen image and a second screen image related to the image forming apparatus, a second memory in which the second screen image is stored in advance. When the first screen image transmitted from the image forming apparatus to the operation unit is displayed on the touch panel display, if a first icon on the first screen image is touched, the position of the first icon is transmitted to the image forming apparatus. When the second screen image stored in the second memory is displayed on the touch panel display, if a second icon on the second screen image is touched, a command indicating the second icon is transmitted to the image forming apparatus.

An image forming apparatus includes a latent image bearer, a toner image forming unit, an intermediate transfer member, a primary transfer member, a secondary transfer member, a switching unit, and control circuitry. The toner image forming unit forms toner images on the latent image bearer. The primary transfer member transfers the toner images on the latent image bearer onto the intermediate transfer member. The secondary transfer member transfers the toner images on the intermediate transfer member onto recording materials. The switching unit switches a position of one of the secondary transfer member and the intermediate transfer member between a first and a second position. The control circuitry controls at least one of a first and a second operation. The control circuitry changes at least one of the first and the second operation when the toner images satisfy a specified abnormal image reduction condition at a first and a second timing.

An image forming apparatus includes a drum cartridge and a controller. The drum cartridge includes a photosensitive drum, a charger and a drum cartridge memory storing a life count value and discharge history information. The controller includes a voltage applying circuit, and an abnormal discharge detection circuit. In a case where the abnormal discharge detection circuit detects an abnormal discharge, the controller does not permit printing in a case where the life count value is equal to or more than a first reference value and a number of abnormal discharges which is included in the discharge history information read from the drum cartridge memory is equal to or more than a particular threshold value, or permits printing in a case where the life count value is equal to or more than the first reference value and the number of abnormal discharges is less than the particular threshold value.

An image forming apparatus includes a storage, circuitry, and an information provider. The storage is configured to temporarily store one or more sheets to be removed without being used in the image forming apparatus. The circuitry is configured to determine whether a manual operation is performed on the image forming apparatus and whether the one or more sheets stored in the storage exceed a given value in number or height. The information provider is configured to provide information urging removal of the one or more sheets from the storage in response to determination by the circuitry that the manual operation is performed and that the one or more sheets stored in the storage exceed the given value in number or height.

An image forming apparatus includes an image forming portion, a fixing portion, and a control portion. The fixing portion forms a nip portion to nip a recording material and includes heat-generating elements along a direction orthogonal to a conveying direction of the recording material. The fixing portion fixes the image on the recording material using heat. The image forming apparatus changes a control target temperature for each heating area heated by each of the heat-generating elements in accordance with the image to be formed on the recording material. When forming the image after a jam clearing process in which the recording material nipped in the nip portion is removed, the control portion changes a distribution of a control target temperature of the whole heater in the direction in which the heat-generating elements are aligned to a second distribution different from a first distribution corresponding to the image.
