摘要:
An image forming apparatus includes an image bearing member for bearing an image, a transfer charging device for transferring the image from the image bearing member onto a recording material at a transfer position, a power source for supplying a voltage to the transfer charging device during an image transfer operation, and a control device for changing an output of the transfer charging device from a first level to a second level prior to arrival of an image area of the image bearing member at the transfer position, wherein the second level is higher than a third level of the output which is a level when the image area is at the transfer position.

A sensor output correction circuit includes an analog-to-digital converter configured to receive an input voltage corresponding to a sensor output of a sensor and a reference voltage that are selectively input to the analog-to-digital converter; and an arithmetic unit configured to correct output data, which is output from the analog-to-digital converter when the input voltage is input to the analog-to-digital converter, based on an output value that is output from the analog-to-digital converter when the reference voltage is input to the analog-to-digital converter. The arithmetic unit includes a multiply adder and a non-restoring divider.

An image forming apparatus includes an electrostatic latent image forming unit for forming an electrostatic latent image on the surface of an image carrier, a developing unit for developing the electrostatic latent image with toner, a transferring unit for transferring a toner image on the image carrier onto a transfer medium in a transfer area, a test pattern forming unit for forming a test pattern, which is made of toner and used for image control, on the transfer medium, and a control unit for detecting the test pattern and executing image control. The transferring unit transfers the test pattern on the transfer medium, which has been subjected to detection, onto the image carrier, and the developing unit recovers the test pattern having been transferred onto the image carrier.

A transfer material carrying member for carrying a transfer material for receiving an image from an image bearing member, includes a first layer having a thickness Ha and a second layer having a thickness of Hb. A change, Xa, due to an ambient condition, in a length of the first layer measured in a direction perpendicular to a thickness direction of the first layer, and a change, Xb, due to the ambient condition, in a length of the second layer measured in a direction perpendicular to a thickness direction of the second layer, satisfy: |Xl−Xb|
摘要:
In an image forming apparatus in which when separating a recording material from a recording-material conveying sheet, the recording-material conveying sheet is pressed and deformed by a pressing member, the pressing member has a convex curved portion contacting the recording-material conveying sheet in a direction orthogonal to the moving direction of the recording-material conveying sheet. It is thereby possible to sufficiently deform the recording-material conveying sheet while preventing it from being permanently deformed or broken.
摘要:
A speaker which is thin but which is capable of providing high-fidelity reproduction and ensuring a suitable level of sound pressure even when it is brought close to a wall. A closed chamber is formed behind one part of a disphragm mounted in an enclosure, and an open chamber is formed behind another part of the diaphragm. At least one voice coil driver unit is connected to the diaphragm. The phase difference between sounds radiated from the front and rear surfaces of the diaphragm is increased as large as possible by using an acoustic duct for the sound radiated through the open chamber, thereby minimizing cancellation of sounds and improving the sound pressure level.
