The developing apparatus has a housing, a developer bearing member rotatably provided at an opening of the housing, a developer containing room, a carrying member for carrying developer from the developer containing room toward the developer bearing member, and a developer accumulating portion provided proximate to the developer bearing member and adapted to accumulate the developer carried by the carrying member. In the developing apparatus, the developer accumulating portion is provided above a rotational center of the carrying member.

Developing apparatus including a developer compression-avoidance feature and image forming apparatus using same

The present invention provides a drive controlling apparatus used in a sheet supplying apparatus including a lift/lower sheet supporting device for supporting a sheet, a sheet supply mechanism for feeding out the sheet supported by the sheet supporting device, a biasing mechanism for biasing the sheet supporting device toward the sheet supply mechanism, and a separating mechanism for separating the sheet supporting device from the sheet supply mechanism in opposition to a biasing force of the biasing mechanism, and wherein the sheet urged against the sheet supply mechanism by the biasing mechanism is fed out by the sheet supply mechanism, said drive controlling apparatus adapted to transmit a driving force for operating the separating mechanism from a drive source and comprising a drive side device connected to the drive source, a driven side device connected to the separating mechanism, and a play setting device for providing a play for not transmitting the driving force within a predetermined range between the drive side device and the driven side device.

Sheet supplying apparatus

A sheet to be fed by a sheet feed roller is loaded on a sheet feed tray, and a side regulating member is disposed so as to be movable in accordance with the sheet size in order to regulate the position of the loaded sheet in the direction of the sheet width. The side regulating member extends downstream from the sheet feed roller in the sheet feeding direction in order to regulate the position of the sheet in the direction of the sheet width, thereby preventing oblique movement of the sheet.
