Abstract: An image forming apparatus includes a developing device, a separating mechanism, and a cooling unit. The developing device includes a developing roller and a developing housing, and is detachably supported by a support frame. The separating mechanism separates the developing roller from a photoconductor drum before the developing device is removed from the support frame. The cooling unit cools the developing device. The developing housing has a bottom plate with high thermal conductivity. The cooling unit includes a heat receiving plate facing the bottom plate, and a cooling tube supported by the heat receiving plate. In the image forming apparatus, when the developing roller is not separated, the bottom plate comes in contact with the cooling tube, and when the developing roller is separated, the bottom plate is separated from the cooling tube.

Abstract: An arm is disposed between a body-side rotary shaft provided in a housing and a cover-side rotary shaft provided in a cover. The arm includes a body-side arm member with one end supported by the body-side rotary shaft, a cover-side arm member with one end supported by the cover-side rotary shaft, a connecting pin configured to connect the other end of the body-side arm member and the other end of the cover-side arm member, a body-side urging member configured to urge the body-side arm member and the cover-side arm member in respective directions of being folded, and a cover-side urging member configured to urge the cover-side arm member toward the cover. When the cover is closed, the body-side arm member and the cover-side arm member overlap each other in an axial direction of the connecting pin.

Abstract: An image forming apparatus performs a transfer residual toner collection operation including a toner adhesion step of allowing transfer residual toner to temporarily adhere to the collecting roller during execution of image forming operation, a toner moving step of moving the transfer residual toner adhered on the collecting roller to an image carrier after the image forming operation is finished, and a toner collecting step of moving the transfer residual toner from the image carrier to an intermediate transfer body and collecting the transfer residual toner. The control unit controls an image forming unit having white background toner amount that is a threshold value or more, to apply the collecting roller with a voltage having the same polarity as toner charge polarity in the toner adhesion step, and to apply the collecting roller with a voltage having opposite polarity to the toner charge polarity in the toner moving step.

Abstract: In the image forming apparatus, a controller applies a collection voltage to a cleaning roller by a voltage application part in image formation process. The controller adjusts the collection voltage applied to the cleaning roller on bases of uncollected toner quantity of a toner image and residual charge of an image carrier, the uncollected toner being part of after-transfer remaining toner which results after formation of the toner image on an outer circumferential surface of the image carrier and transfer of the toner image onto a transfer-objective member, and which has missed being collected by the cleaning roller so as to remain even after one-round rotation of the image carrier.

Abstract: An image forming apparatus includes a housing frame, an image forming unit, a registration unit, and an exposure unit. The housing frame forms a skeleton of a housing. The image forming unit has a photoconductor drum. The registration unit performs skew correction of a sheet. The exposure unit exposes the photoconductor drum. In the image forming apparatus, the registration unit and the exposure unit are adjacent within the housing frame. The registration unit is attached to the housing frame via a pair of flat plates. The registration unit is supported by a plurality of elastic pieces bent up from the pair of flat plates.

Abstract: Devices, such as printers, for rendering compressed digital images, include a deserializer and multiple planar SRLE decoders each configured to transform an applied code from a serial input stream into one or more planar pixel values. The deserializer maintains a cursor position for each of the planar SRLE decoders and increments the cursor position of a corresponding one of the planar SRLE decoders in response to dequeuing a code of the corresponding planar SRLE decoder. The increment is an amount equal to a count of planar pixel values represented by the code. The planar pixel values output from the SRLE decoders are combined into a digital image rendering.
