Connector

A heater is to face a pressure element via a belt and is to heat the belt. The pressure element sandwiches and conveys a sheet together with the belt. The heater includes a substrate, a heat generating element, a couple of electrodes, and a protective layer. There are the electrodes on both sides of the heat generating element in a conveyance direction of the sheet. Both sides of the heat generating element in the conveyance direction are connected to adjacent electrodes.

Heater, fixing device, and image forming apparatus

A heating device according to an embodiment generally includes substrate, blocks, and temperature sensors. The blocks are arranged on the substrate with a gap therebetween in a first direction. The temperature sensors are provided for each of the blocks and detect the temperature of the blocks. The block includes a plurality of first blocks on at least one side in the first direction, and the first block is adjacent to two blocks in the first direction, and the temperature sensor detects temperature of a temperature detection region on the first block, which is closer to the one of the adjacent two blocks being longer in the first direction of the two blocks.

Fixing device and image forming apparatus

An image forming apparatus includes a transfer unit for transferring a toner image onto a sheet, a fixing device for fixing the image, the fixing device including a heating member including a heat generating element and electrodes on both sides of the heat generating element in a sheet conveyance direction and connected to the heat generating element, and a pressure element for pressing against the heating member, and a controller for controlling an adjustment mechanism so that a distance between the heating member and the pressure element becomes a first distance during a fixing process and a second distance larger than the first distance during temperature raising of the heating member, which is conducted before the fixing process.

Image forming apparatus, and adjustment method for distance between heating member and pressure element of fixing device

A heating device according to an embodiment generally includes heat generating parts and temperature sensors. The heat generating parts are divided into a plurality of blocks, so that the plurality of heat generating parts are arranged with a gap therebetween on a substrate in each block. With a temperature detection region provided in each block, the temperature sensors are provided corresponding to the heat generating parts with the gaps being avoided. The temperatures of the heat generating parts are detected by the temperature sensors that are less in number than the plurality of heat generating parts.

Heating device and image forming apparatus

A heater includes a heat-resistant insulating substrate, a plurality of heat generating members arrayed in a first direction on a first surface of the substrate, and a plurality of heat radiating bodies disposed on a surface different from the first surface of the substrate at positions corresponding to gap portions between the heat generating members to passively radiate heat generated thereby.

Heater and heating apparatus

A heater is to face a pressure element via a belt and is to heat the belt. The pressure element sandwiches and conveys a sheet together with the belt. The heater includes a substrate, a heat generating element, and a protective layer. The heat generating element is on the substrate. The protective layer covers the heat generating element and the substrate and whose surface is concave with respect to the pressure element. In the protective layer, a curvature of a top surface of an upstream end in a conveyance direction of the sheet is smaller than a curvature of a top surface of a downstream end in the conveyance direction.
