A recording apparatus includes: an apparatus main body having a recording unit that performs recording onto a recording medium; and a unit body which is provided on an upper side of the apparatus main body, and forms a plurality of boundaries between the unit body and a top of the apparatus main body, wherein a recess that receives liquid entering through a gap is formed for each of the plurality of boundaries.

In accordance with an embodiment, an image forming apparatus comprises a measurement section configured to measure first environmental information of a measurement position in a first period; an acquisition section configured to acquire first external environmental information measured by a first external device; and a controller configured to estimate second environmental information of the measurement position in a second period different from the first period using the first external environmental information, and perform control to execute a maintenance operation based on the second environmental information.

The present invention is related to a condensation prevention type transmission window for a CMS module test chamber, the transmission window being provided at the module test chamber. The condensation prevention type transmission window includes: a multilayer glass panel in which heating wires are coated on upper, lower, left, and right side surfaces thereof; and an air injector provided at each of opposite surfaces of the transmission window to inject air from an upper side edge and/or a lower side edge of the transmission window and to form an air curtain. The present invention provides the condensation prevention type transmission window for a CMS module test chamber, which prevents freezing and fogging on inside and outside surfaces of the transmission window of the CMS module test chamber varying in a temperature range from 40 C. to +125 C.

An image forming apparatus includes an image forming unit, one or more processors, and memory storing instructions that, when executed by the one or more processors, cause the image forming apparatus to perform operations. The image forming unit forms an image on a sheet. The operations include controlling execution of dew condensation elimination processing that is processing for eliminating dew condensation having occurred in the image forming unit. The operations additionally include receiving image data to be printed and restricting, based on a type of a job executed using the received image data, image forming by the image forming unit, in a case where the dew condensation elimination processing is in execution.

In accordance with an embodiment, an image forming apparatus comprises a measurement section configured to measure first environmental information of a measurement position in a first period; an acquisition section configured to acquire first external environmental information measured by a first external device; and a controller configured to estimate second environmental information of the measurement position in a second period different from the first period using the first external environmental information, and perform control to execute a maintenance operation based on the second environmental information.

An image forming apparatus includes a temperature detecting unit configured to detect a temperature outside the image forming apparatus, a storage portion, and a control unit configured to execute a dew condensation eliminating operation for eliminating dew condensation in the image forming apparatus based on a detection result of the temperature detecting unit. The control unit stores, in the storage portion, an execution time of the dew condensation eliminating operation executed when a power supply to the image forming apparatus is stopped during the dew condensation eliminating operation and determines, when the power supply to the image forming apparatus is started, whether or not to execute the dew condensation eliminating operation based on the execution time and a power supply stop continuing time from when the power supply is stopped to when the power supply is started.

An image forming system includes an image forming apparatus that forms an image on a sheet, and a finisher that performs a post-printing process with the sheet. The image forming system comprises: a paper path through which the sheet is passed; an electricity eliminator that is arranged in the upstream side of the finisher to apply at least one agent of water and charge to the sheet; and a hardware processor that controls an application amount of the agent to be applied to the sheet by the electricity eliminator based on an amount of charge which is generated on the sheet when the sheet is passing through the paper path.

An image forming apparatus includes a dew condensation removal unit configured to execute dew condensation removal processing if it is determined that dew condensation may have occurred in the image forming apparatus, a reception unit configured to receive a print job for instructing execution of print processing, a restriction unit configured to restrict the execution of the print processing during execution of the dew condensation removal processing, a display control unit configured to control a display unit to display a selection screen for selecting whether to execute or cancel the print processing based on the print job if the print job is received during the execution of the dew condensation removal processing, and a print control unit configured to control the print processing to be executed after completion of the dew condensation removal processing if the execution of the print processing is selected.

In accordance with an embodiment, an image forming apparatus comprises a measurement section configured to measure first environmental information of a measurement position in a first period; an acquisition section configured to acquire first external environmental information measured by a first external device; and a controller configured to estimate second environmental information of the measurement position in a second period different from the first period using the first external environmental information, and perform control to execute a maintenance operation based on the second environmental information.
