摘要： An image forming apparatus capable of executing continuous image forming operation forming images on more than one page includes a temperature detector that detects internal or surrounding temperature of a developing device correspondingly changing to temperature of a developer bearer. A temperature information acquiring device acquires information of ambient temperature outside of the image forming apparatus. A controller switches a current operation mode to an intermittent image forming operation mode intermittently including a braking time period not to allow image formation and cancels the intermittent image forming operation mode in accordance with detection result of the temperature detector. The intermittent image forming operation mode allowed to continuously form images only on a prescribed limited number of sheets. The controller varies the braking time period in accordance with the ambient temperature detected by the temperature information acquiring device.

摘要： An image forming apparatus includes image bearers, developing devices, developer containers, and developer supply devices. The image bearers are arranged side by side along a movement direction of an intermediate transferor or a sheet. The developing devices, the developer containers, and the developer supply devices are configured to be rearrangeable for each color in the movement direction in a manner that one or each of a developing device, a developer container, and a developer supply device corresponding to each color of the different colors is detached from and attached to the image forming apparatus, separately from a rest of the developing device, the developer container, and the developer supply device. The image forming apparatus is configured to be available for use when colors of the developing device, the developer container, and the developer supply device correspond to each other after rearrangement.

摘要： A powder container for an image forming apparatus includes: a rotatable powder storage storing powder; an opening on one end of the powder storage, through which a nozzle can be inserted; and a scooping portion to scoop up powder on an opening side, and supply the powder to a powder receiving hole of the nozzle when the powder storage rotates. The scooping portion includes a scooping surface extending inwardly from an inner wall surface of the powder storage and an inner end portion extending in a rotation axis direction of the powder storage, with an edge approximately parallel to the rotation axis. In a cross-section perpendicular to the rotation axis, the scooping surface is inclined toward an upstream side in a rotation direction of the powder storage with respect to a virtual line that passes through the rotation axis and is tangent to the edge of the inner end portion.
