A camera system includes a lens assembly and image processing electronics internal to the camera housing and thermally coupled to the battery assembly. The battery assembly is sensitive to low ambient temperatures and may become damaged if the temperature of the assembly becomes sufficiently low. The camera system comprises a thermal management system that dissipates heat from electronic components of the camera to increase or maintain the temperature of the battery assembly. The thermal management configures the electronic components in different modes to create a step-wise increase of the resistive heat generated in the camera system and thereby increase the temperature of the components in the camera system.

A sheet conveyance apparatus includes: a speed detection roller that detects a conveyance speed of a sheet by coming into contact with the sheet being conveyed and being driven to rotate; and a hardware processor that performs temperature control to make an ambient temperature of the speed detection roller a predetermined temperature.

An image forming apparatus includes an image formation unit, a detection unit, a storage unit, and a control unit. When the detection unit outputs a second output value when a second recording material, which is different from a first recording material is detected, in a state where the storage unit stores a first output value output by the detection unit upon detection of the first recording material, the control unit controls an image forming condition based on at least the first output value if a differential value between the first output value and the second output value is smaller than a predetermined threshold value and controls the image forming condition based on the second output value without using the first output value if the differential value is greater than the predetermined threshold value.

An image forming apparatus includes an image reading unit, a fixing unit, a time setting unit, and a control unit. The image reading unit moves a running body having an onboard optical system. The fixing unit heats toner transferred onto the print medium and applies pressure on the heated toner with respect to the print medium to fix the toner. The time setting unit sets an estimated time when use of the image forming apparatus starts. The control unit controls the image reading unit, the fixing unit, and the time setting unit. The control unit, prior to the set estimated start-of-use time by a predetermined period set in advance, activates the image reading unit to detect whether condensation has occurred in the optical system, heats the fixing unit in response to a detection of occurrence of condensation, and stops the heating before the estimated start-of-use time.

An information processing apparatus includes a processor configured to set a state of a fixing device in a case where a state of an image forming apparatus including the fixing device transitions to a power saving state to be different depending on a property of the imaging forming apparatus.

An image forming apparatus, includes: a media sensor that detects a sheet type; a fixer that fixes the image on a sheet; a storage that stores a fixing temperature for each sheet type; and a hardware processor that controls power supplied to the fixer by pulse-width modulation (PWM) control and controls a temperature of the fixer to the fixing temperature corresponding to the sheet type detected by the media sensor.

An image forming apparatus includes a heater, first control circuitry, second control circuitry, and a detector. The heater is configured to heat an inside of the apparatus. The first control circuitry is configured to cause the apparatus to be in a standby state, a sleep state having smaller power consumption than the standby state, or a deep sleep state having smaller power consumption than the sleep state. The second control circuitry is configured to control an operation of the heater. The detector is configured to detect humidity of the inside of the apparatus. The first control circuitry causes the apparatus in the deep sleep state to periodically and temporarily return to the sleep state, and the second control circuitry operates the heater according to the humidity detected by the detector in the sleep state to which the apparatus has returned from the deep sleep state.
