摘要:
An image forming apparatus includes a translation cam having a cam surface configured to move a developing roller from a contact position contacting a photosensitive member to a retracted position retracted from the photosensitive member and further having a holding surface configured to hold the developing roller at the retracted position. The image forming apparatus further includes a first engaging portion. The translation cam includes a second engaging portion. The first engaging portion and the second engaging portion are configured to engage each other before a functioning surface of the translation cam is switched from the holding surface to the cam surface.

An image forming apparatus includes a developing roller, a conveyance roller which conveys a sheet; a driving source which provides a driving force to the developing roller and the conveyance roller, a developing driving gear mechanism which transmits the driving force of the driving source to the developing roller, and a conveyance driving gear mechanism which transmits the driving force of the driving source to the conveyance roller. The developing driving gear mechanism includes a developing driving switching mechanism which causes a rotating direction of the developing roller when the first driving source rotates in a first direction to be same as the rotating direction of the developing roller when the first driving source rotates in a second direction reverse to the first direction.

An image forming apparatus includes a driving source, a supply roller which supplies a recording sheet, a fixing device, a fixing driving gear mechanism which transmits a driving force of the driving source to the fixing device, a supply driving gear mechanism which transmits the driving force to the supply roller, and a control device. The control device controls the driving source to rotate in one direction when a temperature of the fixing device exceeds a predetermined temperature, and to rotate in a reverse direction when the temperature is the predetermined temperature or lower. The fixing driving gear mechanism includes a mechanism which interrupts a transmission of the driving force when rotating in the reverse direction. The supply driving gear mechanism includes a mechanism which causes a rotating direction of the supply roller to be same when the driving source rotates in both directions.

A ventilating fan including a ventilating fan body provided with a motor, a frame having ventilating air outlets, and fan blades, an adapter and an electric element box. The ventilating air outlets include a top air outlet provided on a top face of the frame of the ventilating fan and a side air outlet provided on a side face of the frame of the ventilating fan which are communicated with each other. The adapter is provided with a raised structure adapted to the ventilating air outlet. With this structure, the height of the ventilating fan is reduced while air volume is ensured, so that the ventilating fan is adapted to be mounted onto various ceilings, and the cost can be saved while mounting of the adapter is simplified.

To provide a terminal-attached plate, which is capable of providing a connector fitting portion at only one end portion of a battery module, and is capable of preventing the battery module from being made thick, and to provide a plate assembly, and a battery module. A battery module includes a single-cell stack and a plate assembly including stacked plates turned back alternately and connected to an end of the stack, each plate including a joining portion, a plate supporting portion, a terminal including a connecting portion connected to a tab of the battery and a contact portion connected to a connector, and a hood member protecting the contact portion, wherein the hood member is disposed at a position offset to an end portion side of the plate from a center in a longitudinal direction of the plate.

An image forming apparatus may include controls for changing a state of a developing roller from a stopped state to a rotating state. The change in state may be used to avoid deterioration of toner and/or a surface of the developing roller. Changes in state may occur at various times including at a timing corresponding to an outside of an image formation area, a timing corresponding to an inside of an image formation area and the like. In one arrangement, a first developing roller may continue to rotate (e.g., during monochrome printing), while one or more other developing rollers are switched between a stopped state and a rotating state. Alternatively or additionally, a roller which is caused to change states may remain stopped between the timing corresponding to a rear end of an image formation area and a timing corresponding to a front end of an immediately subsequent image formation area.

A detergent for cleaning media is provided. The detergent comprises deionized water, between about 1% and about 5% by weight of a nonionic surfactant having an hydrophile/lipophile balance (HLB) value between about 10 and about 20, and an ethoxylation level between about 5 and about 20, between about 1% and about 5% by weight of a dispersing agent, between about 3% and about 10% by weight of a chelating agent comprising phosphonic acid, and between about 2% and about 6% by weight of an inorganic salt.
